As a friend to her. You are her confidant. Ya its messed up and you should try and maybe talk her about how you feel, but its none of your business really.
Now if your good friends with her husband that’s a hard one. Who are you more loyal to really?

Well if you feel you have to ask, you already know what you should do, you just need the guts to do it. Or just tell her no. She’s your friend, she will understand that you are not comfortable.

Cheating is the most disrespectful and hurtful thing a person can do to someone they are suppose to love. Obviously she has checked out of her marriage and he has every right to know what is going on. It’s time to have an adult conversation with your friend to let her know how you feel. She needs to come clean or you need to & wash your hands of that friendship. I don’t deal with shady stuff like that. Playing with a person’s heart & emotions is pure evil.

So about 15 years ago I had a similar experience. They weren’t married but engaged. My best friend at the time was sleeping with our other friend of the group. She had been off and on with him since we were kids. Well she was engaged to one of my good friends from grade school. The had been together about 5 years at this point. I was torn. She was my best friend but he also had my respect and we went waaay back. Same with the guy she was cheating on him with. Well one night I broke down and I told her man. He was furious at me for not telling him sooner. She disowned me because I broke her trust in the situation.
Now fast forward 5 years down the road. He ends up with another good friend of mine. We make amends. He marries her and has 2 beautiful children. Got a job as a state patrol man, house the whole 9 yards. He thanked me.
She now has 7 children and is married. She ended up going with another one of my highschool friends and they got married and live pretty well.
She thanked me to years later.
So initially I lost friends but in the end they came back and I earned more trust and respect from both of them for speaking up. It’s a shitty position to put friends in.

Karma usually will figure her situation out. And secrets never stay secret and they always find some way of coming out. You never kno the reason why but bring It up and tell her how much this bothers you and she needs to leave him. Cause it’s not fair for him either. People who say to mind their business are probably the kind of people who turn a blind eye on relationship abuse because it’s " not my place to say". I had a friend similar to this and she went behind my back and slept with my ex who broke up with me a little less then a week and then my new date. Honestly I’d tell him cause if that was me id like to know asap instead of looking like a damn fool BC everyone around me knows and in acting happy.

talk to her first. Ya she’s your best friend but this isn’t about loyalty it’s respect. And her husband deserves that respect. I’d be pissed if my husbands best friend kept from me that he was cheating . What she’s doing is wrong and if you know and allow her to keep hurting him you are just as much in the wrong

Is not your business to interfere in their relationship but I would tell my best friend that I don’t like to do that shit to people and as sure as hell will not cover it up! If people know she is doing it then they may think you are the same! You don’t want to be related to that kind of people!

Go on the trip and take that time to tell your best friend how you feel. I wouldn’t tell her husband though, I’d tell her that she needs to do it. If she’s that unhappy in her marriage, maybe she’ll do the right thing and talk to him and leave. If she’s TRULY your beat friend, then you can be there to help her get through the separation and divorce!

You never know what happens behind closed doors and not to make it excusable because it’s not but are there any warning signs that your friends marriage could be in trouble aside from this? Maybe you need to have a heart to heart with her like suggested and get to the bottom of how she’s feeling and why she’d be wanting to do this. I wouldn’t tell her husband because it sounds like the deed hasn’t been done, but I would definitely try to talk her out of it before she does. She doesn’t want that kinda guilt on her soul. Best of luck.

If she was truly your friend, she wouldn’t have to ask or even assume you would be ok with her cheating on your girls getaway. I know I would never put one of my friends in an awkward position like that even if it didn’t bother me. Why cheat? Just tell your husband the truth, end the relationship, and then date.

I have a feeling my response won’t go over well but here goes…
Maybe its not cheating. Maybe they are polyamorous. Maybe he already knows she’s seeing someone else because it’s part of their relationship.
Tell her you can’t live like that. Keeping secret like that is damaging to your health. You’re condoning it. It’s like knowing who robbed the bank but not saying anything. You’re an accomplice now. Tell her to tell her husband and be an honest decent person

To me that’s seriously unhealthy and I wouldn’t not accept me being a scape goat so someone can lie to their husband… I don’t like liars and I don’t like people that cheat. Best friend or not tell her how you feel and she either is your best friend and doesn’t use you like that or she isn’t your best friend and was using you…
Idk… my husband never cheated on me with a human… He cheated on me with life. Waste of my time🙄 idk how I was stupid but it is what it is… you should just give info, screenshots and everything to her husband. Proof as well. Don’t just tell him without receipts but he has a right to know what’s going on and don’t let him be blind.
Stay home don’t say anything ,let him find out on his own ,don’t get involved in her mess .

Don’t go! I had a friend that did the same. While we were together at her house. While the husbands went to the store her and another of her friends called their cheaters. Told me come on .
I refused and as soon as the guys returned I told mine I wasn’t feeling good and wanted to leave. We did. I’ll never be a part of something I don’t believe in. As for telling her husband that’s dependent on your friendship.
I told my husband the truth so if he told her husband it was on him. Also it was my husband’s friend. I met after we were together.
They will blame you when they work it out. Trust me.
Your best friend confides in you and trusts you. I wouldn’t do her like that. When I create a friendship, I am loyal to them. Instead, create a boundary with her. Communicate that it bothers you and you don’t agree with it and keep that part of the conversation out of the friendship. As far as morally, let her life play out as it must. Don’t interfere…the universe will correct itself. Best friends are supposed to be there to tell you EVERYTHING…the good…the bad…the ugly. If you are considering getting in the middle of it, then you should reevaluate your role in the friendship. RIDE OR DIE….basically.

Girl, don’t listen to some of these people because their response is a double standard and that’s what’s wrong with our society… do what YOU think is right, but have some evidence to prove it if you do wind up telling her husband. I always tell my friends that if they’re gonna do some shady shit, I don’t want any part of it, therefore, don’t tell me about it or talk about it around me because when you ask my opinion, most times, you’re not gonna like the response you get… IF YOU’RE NOT HAPPY IN YOUR RELATIONSHIP, YOU CAN LITERALLY JUST FXCKING LEAVE! Idc what anybody says. Nobody deserves to lay awake at night and wonder why they’re not good enough… you’re a sorry ass human being if you make somebody feel like that

If it was my friend I would make sure I had proof and give it to her husband. My ex husband cheated on me and 3 of my friends knew. No one had the guts to tell me. Not only is he my ex they are ex friends. I don’t want to be friends with people who cheat they are trash.

STAY OUT OF IT. ITS NONE OF YOUR BUSINESS. The truth will come 2 light 1 way or another. Either her guilt will get her considering she had 2 tell u or u found out, if that’s the case he will eventually find it himself. she’s bound 2 slip because she slipped with u. Go or don’t it’s ur choice. If it’s going 2 bother u 2 overlook it then don’t go, if u can overlook it and have a good time go. The trip is about U 2 having fun, not supposed 2 be about her personal choices. I’d ask if that’s what it is supposed 2 be and decide on going based on her answer.

Mind your own business is the best policy. It doesn’t matter that your friends. Everybody makes mistakes. You can’t always help others. But don’t go along with her and pretend you’re not seeing anything. Step out of his life too just like you said you don’t want to be on her side either. Sad but true.

You should tell her you don’t want to go because you aren’t comfortable with her choice to cheat. She’ll likely make it about herself, but you gotta respect your own boundaries and as your best friend she’s either gonna respectfully accept your position an go on her cheater trip without you, or she’ll project her negative feelings into you because she knows what she’s doing is wrong but doesn’t want to own that, or she’ll become less of your best friend and it may drive a wedge between you. But in my opinion, if she doesn’t align with you they way she once did, some division between you two might be a blessing in disguise. Nonetheless, stay true to you. Lastly, no, I do not think it is your place to tell her husband unless you value his friendship over hers and can live with the consequences of that choice (ie damaging your friendship with her)
Stay out of it, don’t be a shitty friend. He’ll find out on his own eventually

I wouldn’t say anything, best to say out of it. but also wouldn’t go on the trip and contribute to the lie. I couldn’t look my friend’s husband in the eyes after knowing that, so I’d probably just disconnect from that friend all together. Regardless of the 10 years associating with a cheater when you know doesn’t make you any better of a person.
