What wasnt meant for you was meant to be for somebody else and that happened to be your sister. Weird? Yes, but it’s not your fault fate had plans for you sister… you just got in the way first… 
You said he was you X so whats the problem
I’d find a new sister.
Idk bout the hole kids part but I got 2sisters way younger then me thank god. There almost same age but one of my sis is marrying my other sis ex but there still talkin. But hate me tho
I didn’t know snakes got married. I need to watch more Animal Planet. smh. In all seriousness though neither one of them are worth your time or anxiety. The day of the wedding go get your best lady friends and have a night out on the town. You do you. You can still be there for your nieces or nephews without being party to your sister’s betrayal.
They both sound like terrible people. Everyone else on here is trying to sound so proper. But that’s some snake sh#t. And that relationship isn’t gonna last. Don’t even stress. And I wouldn’t trust your sister at all. I’d be more upset with her than him. He’s just some guy she’s your sister you deserved more from her than her getting pregnant by a man you were in love with. She sounds like someone I wouldn’t want in my life. Horrible.
Move on and get over it. They have 2 children what did you suppose would happen? If you were so mad at her you would have long cut her off when they got together and this wouldn’t even be a conversation right now. So the problem seems to be that they are getting married, maybe you’re just jealous. He’s your ex, your sister didn’t date him when you guys were together, so stop being so entitled and grow up. He wasn’t meant for you but clearly for your sister.
Why do I feel like I’ve seen a very similar post in the last couple of days…?? You’ve already answered your own question…you don’t want to go because you feel betrayed by your sister and your ex….them you shouldn’t go
Did your sister cause the break up ?Your sister will always be part of you but a man can say he loves you today and next day ask for divorce .Go to wedding wish her the best and move on God has the right man for you .
Naw I wouldn’t speak to my sister again if she did that…

No I wouldn’t go , there was no reason for her to do that to you
One of my friends MARRIED her DAUGHTERS baby daddy. Its so weird and gross. 
Please do not let the “shes still your sister” comments get to you cus idc if it was aunt, grandma cousin or mom you just don’t do that 
if you don’t wanna go DONT GO babe. Your feelings are completely valid 
Move on lol. It’s been long enough for 2 kids. Go meet someone new and leave the guy alone. Your sister would hopefully support you if you got married, it sucks that she chose your ex out of all people though.

I feel for you I’m sorry you’re having to go through this! I’ve been trying to sort out my own feelings and try to control my attitude watching my twins go through a similar situation. If you don’t support their wedding and you don’t feel comfortable, there’s nothing saying that you have to go and it would be very understandable why if you didn’t. Mental health is more important now than ever, take care of yours 1st! Hugs

Oh brother. If he’s an ex I’d laugh at my sister for being so dumb!
They’ve had two kids by now and you’re mad about a wedding? Why didn’t your relationship work out? Are they happy?
I want to add, you don’t need anybody else to justify your feelings. You are entitled to feel the way you feel. Don’t ever doubt that and don’t ever lose sight that you’re important
Grow up! Clearly they have had two kids together and now it’s bothering you…

Help a mama out and respond anonymously on our forum. My sister married my ex boyfriend and had kids with him: Advice?
He was your boyfriend not your husband. Move on, next chapter.
He is ur x so u should not care
You always got to know both sides of the story to form an opinion. I have somewhat the same scenario when I was very young 20 at a club I had a man start walking towards my sister and I at that moment someone asked her to dance so he came over and asked me to dance we hit it off extremely well had a very good time and we ended up dating for about a year and I felt this could be really something. He then went away on business I met someone else I decided to marry even though I didn’t feel the same deep feelings.
I found out years later he went to my sister try to find out about me actually tried to stop the wedding she refused to give him any information and she made a date with him acted like she was going to give him the information. I don’t think I would have married my husband if I knew how’s my past boyfriends feeling. I ended divorcing my husband quite soon after our marriage.
Now do you blame me for accepting the dance and starting a relationship when he was on his way to meet my sister or blame my sister when she literally screwed up my life by not letting him to stop the wedding.?
Ha! You’re not going to believe this But…
Need more details…how long after you broke up did they get together, etc.
Please stop posting complete garbage this is ridiculous
Nothing like sloppy seconds. 
If you don’t want to go don’t go. It will only make you feel bad.
This sounds like a Jerry Springer show. But I say don’t go.
Hell no I wouldn’t go to the wedding
I agree go have a spa day
F$&@ that bitch! And I’d tell anyone that supports it they can pound sand too!

Your sister sounds like a bitch, I wouldn’t go to the wedding either!
I’ve seen so many posts in this group with sisters and their men. It seems to be the norm…all I can say is move on it’s your sisters …if it happens it happens… Love your family. These men weren’t your husband’s they were boyfriend’s …
Don’t let it to allow separation in family love. Some have children involved… I myself never saw interest in any sister cousin friends men … But I guess things happens move on and maybe you will find a man not a boyfriend that will suit your fancy …
According to your description above they were married, meaning already took their vows because that’s what married means, so what wedding do you plan on attending if you had or hadn’t already???
So you could stay home and keep out they’re business… or you could go to the wedding make a scene throw the cake at her eat the entire buffet and trash the place… completely up to you😊

Time to move on. He is your ex for a reason
Although your sister crossed a line and you have a right to you feelings you need to find a way to push through. You will have no peace until you forgive them.
girl some of these people will have you believe that you should forgive and forget! Just because family is blood doesn’t mean you can’t cut ties with them. To me this is so disrespectful and I wouldn’t want any part in her wedding or life. People think just because someone is family that you owe them something, you DON’T. If it disrupts your peace LEAVE it behind. I don’t know your situation but sometimes you need a whole new scenery and to live your happiness. Don’t dwell on it and if you need to talk to someone therapy can be so therapeutic some of these comments are just gross. I can tell a lot of people are okay with this level of disrespect. Not me! I’ve been through enough family trauma to know that family doesn’t mean anything unless they truly respect your boundaries.

Sometimes people come into our lives for many reason. Sounds to me like they love one another and are happy. It didnt work with you guys. I don’t think that should hinder you from a relationship with your sister or the kids. Move past it and move on. I had a love for someone and dated for 6 years. After a year my good friend got with him and you know what it stung for a bit. But then I realized how happy they were. How in love they were and I was happy for them. Be happy. Happy he found someone good for him and happy for your sister.

It doesn’t matter if is your sister or whoever in your family. Your feelings matter. Do what you feel to do, if your heart hurts and they didn’t care, stay away from them. Real family doesn’t do that. Your feelings are valid and she should have respected that , I would distance from her and seek healing out of that selfish and care less circle. Let them know how you feel and get away from them, cut all ties and move on with people who really loves you and respect your heart and boundaries.

Your feeling are valid and you don’t have to go if you don’t want too. She should understand that. That said, if they have two kids together it’s been a while and for YOUR sake I’d try to make peace with yourself. I’m not saying forgive and for get, just forgive enough that you no longer care and whatever happens happens.

If you still love him it’s pretty awful that they are together. If it’s like the other lady from last week where it’s been years since the break, maybe counseling will help reconcile your feelings? Do you have kids with him?
I think it is acceptable to not attend this particular wedding.
Throw the whole sister away!

Why would you go or even consider going If you’re in love with your sister’s husband? Stay home, there’s nothing saying that you have to go and and make yourself miserable. Many weddings are the beginning of the end of many friendships,why add to the misery?

I read some of the other comments and I agreed with several…pro and con.then I reread your words…you said your sister…ended up with…your ex( sounds like it wasnt right away…and they have…two children( so not just a casual thing they had not one but two so they have been together some time and are now deciding to wed.) You also mention you “had” strong love for him which says past tense…the keys wors I’m reading are…(she ended up with and you had) as someone said he is an ex for a reason hes not your person) whether you go or not is for you to decided. What does your heart tell you…not the ego but your heart. Maybe just maybe he was brought into your life to end up with your sister…you had strong love which means you saw good in him and that’s what you’d want for your sister someone good especially since he is the father of your nieces or nephew he is family . They are your blood children are a blessing. If you are STILL IN LOVE with him that is something else but if he was just a chapter in your life… someone else is out there waiting for you and you can feel good that you played an important part in creating a loving family.
