Do I tell my Brother in Law my sister has a boyfriend?

My sister and husband have been married for 16 years. They were good the first 8. My brother in law is a good guy. Then things started to go south. My sister cheated on her husband and had a bf (a married man) a few years ago and he found out and she swore it was over. They tried to work on their marriage but nothing really happened. They got a little better but still bad. Her husband has suffered from depression in the past as well. Come to find out my sister and her bf never broke up. All of her kids know about the boyfriend and she even brings the kids around the boyfriend. However, her husband doesn’t know. Now to top it off - the oldest, she is 14 - just saw a doctor and is depressed bc she has to keep so many secrets my sister tells her and can’t handle the pettiness between my sister and her husband.

Do I tell my sisters husband about her bf? Or do I mind my business even though it is affecting the kids….

Since it’s affecting the kids, I would tell him. There’s no reason that your sister needed to involve the kids, let alone make them lie for her. No offense since it’s your sister, but he needs to leave her. He already has depression, living like that will not help it. There’s gonna be two people, the ones who will say back your sister up and the other saying to tell him. I say tell him. Him. & your nieces / nephews deserve better.

Def tell her if she doesn’t tell him you will! When the kids health is now being affected, she’s WRONG. And needs to know that.

Kids first tell him so they can move on and be happy

I would say tell him, but don’t expect any thanks for it. You’ll get the blame of destroying a family (probably by the whole family) even though it is 100% your sisters fault. This is obviously bothering you though so tell him (for your own sake if nothing else) and just keep in mind that you are doing the right thing.

All of these years I’m sure he knows. She’s wrong for involving her children and if anyone tells, it should be the children since the mom has them involved. Especially the oldest since she’s the one seemingly affected the most.

Honestly, it’s not your business to tell. Especially considering that’s your sister…. :unamused:
Y’all do too much sometimes.

Ps: I let y’all be great because I don’t like Facebook Jail. :relieved: peace and love.

I’d tell him. Those babies shouldn’t have to suffer nor does anyone deserve to be cheated on. If he knows and he’s ok with it awesome, if not, at least he then knows. Plus can get the kids some help and or work something out with your sister so it’s not negatively impacting the kids.

That’s a terrible thing to do to your kids, to put them in that position…I know first hand

I would tell him AND I’d rock my sisters shit. She’s fucking with her kids too.

That’s a complicated one but what I would do first is confront your sister as to what you know about what’s going on. Have her explain the details if she is willing to and have her see how the actions that are going on are affecting the kids. I feel like the husband still has his suspicions if he doesn’t already know what’s going on. Good luck

Mind you business i went thru similar shit being that child n it was 30 times worse on us once people started opening their traps .

Let her handle her own marriage n children. I was very resentful to my mom about it for a long time but at the end of the day they worked thru it n I couldn’t imagine them not being together now as he is my bonus dad

Tell him. Especially with her involving their children. That is wrong on so many levels.

You’re probably going to loose your sister over this. It doesn’t sound like she’s much of a loss though. I’d tell him. I’d also help him get custody if I could. Cheaters are not morally capable to raising children.

Get that 14 year old outta there and look after her

I would definitely go to your sister first and tell her it’s time to make a choice, if she’s happier with the boyfriend then she needs to let her husband know their marriage is over so he can move on and the children should have never had that burden put on them. Your sister needs to be honest so everyone can rebuild

I would tell him. It’s not fair to be in a marriage of 3 as Diana would say. To put those kids through that is emotional and mental abuse. You could always tell him and ask him not to say it was you that told him. Then tell him to do his own research and find out for himself. Those poor kids It’s more than unfair.

8 years and you think he doesn’t know? He knows. He might be in denial to try to keep his family together, but he knows. Support your niece, talk to your sister, be honest if asked what you know…but to go out of your way to tell him seems like you’re just looking for drama. You don’t need to be his hero. You know you’ll destroy your relationship with your sister, but it seems like you don’t care too much about her anyway if you can’t even sit down and talk with her before going behind her back to ruin their marriage.

You talk to your sister first about how her actions are negatively affecting her kids and let her decided to do the right thing… if she doesn’t than yes I’d tell the husband. Their daughter doesn’t deserve to deal with her mom’s issues and shouldn’t have to keep her moms secrets. I’m surprised she hasn’t told her dad herself

I would sit your sister down and tell her what she is doing to her child. That is not fair to her. I would tell her that she is causing her child pain by doing this and you won’t stand for it. Either she tells her husband or you will and I would give her a couple days to tell him and if she doesn’t I would. I hate when adults drag their innocent children into it. My parents did that to me at 18 when they divorced and it was awful. I couldn’t imagine being 14 and having to do that.

I would say to her, tell him now or I will!

For the kids safety and sanity. Absolutely tell him.

I had to keep that secret before and now resent the person a little bit who told me to hide it.

Tell the husband bc talking to her is a waste of time - she has been lying for years about an ended relationship that hadn’t and now she has her children involved in the cruelty and deceit and it’s affecting there mental health as well - def have proof of what is going on to help him cope better and to know that you are not doing it as anything but to help him and his children - she deserves whatever comes - this is just wrong on her part from the get go.

Tell him… What if it was you? And thoes poor children!

I would go to your sister first and express your concern for the kids and tell her that your going to her husband if she doesn’t. This way she understands that your concerned about your nieces/nephews, it’s ultimately not fair and inappropriate. It also gives her the opportunity to do it herself and hopefully not damage your relationship with your sister too much, and possibly give her and her husband the chance to separate smoothly and respectfully. Either way its a horrible situation for everyone. As adults we
Make choices and choices come with consequences.

You’re right, she wrong…
Bust her a@@ out and tell her to make things right or YOU WILL! Then find the BF wife and tell her what’s going on…
I’d also advise her to seek therapy clearly she needs it…hell the whole family will after this comes out…those poor kids and her poor husband…SMH Your sister seems very selfish and by what you say doesn’t appear to care who’s feelings she hurts…END this sh*t now so you can move on too!

I would talk to my sister and give her an opportunity to come clean while letting her know if she doesn’t I will. I would not be ok with my niece or nephews having to live through that and grow up like that so I would definitely step in.

I would sit her down and talk to her, and give her the chance to tell him herself. If she doesn’t, then you should. Anybody deserves to know when they’re being deceived. But in any case it would be best if it came from the deceiver coming clean with honesty. Best of luck gf

If you wanna keep out of it but still let him know. Just give him a little information so he can figure it out. I would do it in person so it can’t be traced back to you.

If your married sister has a boyfriend, that marriage has been over for a long time… the fact that she’s bringing the guy around the kids clearly states she has no respect for the man she is married to and is showing the kids to disrespect their father.

  • I would personally say something. It’s affecting the kids and once my nieces and nephews are affected by my siblings actions, that is when I get involved.

Tell him, you said yourself, he’s a good guy. He clearly deserves better than what your sister is giving him, let him move on. Especially as it is effecting the kids. Get it all out in open, things could get worse for the kids and thats not fair on them. Depression is not a nice thing to go through yourself let alone seeing kids go through it (talking from experience, my daughter was diagnosed with depression when she was 5). The husband and the kids deserve better, so much better, and so do you, your also keeping this for your sister. Its not healthy, tell him before it’s too late for everyone in the situation.

I would have a talk with your sister. But don’t accuse her with no proof. Make sure you somehow have proof of her affair.

Let her know if she doesn’t tell the husband, you will along with showing him proof.

I would smack my sister tell her to be honest with her man. If she gives excuses tell her you will do what is best for the children and tell her husband. Then tell the children they can come to you for anything because they do not deserve to be involved in such things. At that point I wouldnt care if my relationship with my sister faded because her kids are more important. My sister knows I would do that to her and knows she can not keep her kids away from me. For the kids sake give her an ultimatum

Talking to her sister first is not the answer. Her sister will just lie again. Her sister will never be satisfied with whom she is married to. Some people are just that way. But I wouldn’t tell her husband. You will be the outcast if you tell. So let her husband find out for himself.

Back RTF away from this. The odd are that after you tell all, after all the crying and recriminations and everything else…your sister and her hubby patch it up. You said yourself that he found out once and they got back together. You could find yourself in the difficult and heartbreaking position of having both of them angry with you for sticking your nose in their business. Be an impartial shoulder to cry on, but please, please, stay out of this.

I don’t think you should tell the husband but I do think you should have s talk with her kids letting them know they are too young to be keeping grown ups secrets and stressing so they need to do what makes them feel better whether it’s telling or just knowing they won’t be responsible if he finds out!

I would definitely tell him and let the cards fall where they will. They are your family now as well because of her, and she is mentally tearing that family down so that she can be happy with someone else’s husband… The kids being involved is so much worse because they see how the situation is effecting their dad, while also seeing her get to be living happily in her secret world of lies, and can’t say a word. All of this is so heartbreaking and toxic for everyone involved. Please tell him right now so that he can move on and work on getting the kids and himself to a better place mentally. In my opinion, their future health and happiness is worth more than her possibly getting upset at first because you let it all out.

Her idiocy and selfishness is hurting her children. CHILDREN COME FIRST. Tell her husband and I hope her puts her out. Smh :woman_facepalming:t3:
