Best friend is cheating on her boyfriend!

Well, this is a tricky one.

I'd be so disappointed if my close friends acted this way.

I guess it depends on your relationship with your best friends boyfriend. Are you two actually close? Are you genuine friends with him also?

If so, then as a friend to him, you do have some sort of duty and loyalty.

If he is just someone you know because of your best friend, then it becomes more difficult to make that judgement call.

Morally, yes, he has a right to know.

If you do tell him, you'd be ending your friendship with your friend.

I suggest that you keep on talking with your best friend and keep on trying to convince her to stop cheating on her boyfriend. Don't just stop cos she brushed you off once or twice.

If you care for her, then you'll keep on pointing out to her that this wrong. Hopefully the message gets through.

The bf is only a good friend to me, he's someone I can go to when I'm down because he knows how to make me smile but my bff was the only person in my life who had been there at my lowest point. She was the only person who helped me out when I was depressed and angry at myself and I can't betray that. She was there for me shouldn't I be there for her? And yes I have seen her cheat on him when we went to a party. I have asked plenty of times to just go and tell him straight about this but she claims that she doesn't want to until uni! I don't know why she wants to lead him on till then because every time I ask she said that she doesn't want to lose him and she does actually like and wants him all to herself. Selfish I know! Now what do I do? Sit back and see how this goes? Or snake on her?

You should seduce her boyfriend.

Have a proper talk with her. Ask her how she would feel if she really liked someone and found out they'd been cheating on her loads. Ask her if she even feels guilty about it.

She can't expect you to keep basically covering for her, its not fair on you, and it definitely isn't fair on him.

If you value your friendship more, keep it quiet. If you feel you can't keep seeing her lying to him, give her one more chance, tell her you'll tell him if she doesn't. If you do that, don't back out, show her you're completely serious, and she may panic and tell him herself.

If you're going to tell him, get evidence of some kind. It's just going to turn into "he said, she said", or in this case, "she said, she said" if your friend denies the accusation.

Surprised by the responses, I think you should always be loyal to your mates, even if they're in the wrong. I've known friends to cheat (though I've never really known the girlfriend), and I've encouraged them to fess up or break up, but never considered grassing.

Also, surprising how many people think she should just break up a friendship over this. Clearly doesn't mean much to some people to be a mate.

Hey guys, so thanks for all your thoughts on this issue but I've decided that I'm not going to help the girl who slept with my bf whilst I was going out with him. Heck, I probably don't care now. It's funny how, the one person you trust in this world with all your heart turns out to be the biggest bitch of all. I didn't expect it coming but when we were having a row over the weekend about her telling her bf about the countless amount of times she slept with other guys she decided to tell me how she slept with mine last month. I don't know if she purposely said it so that she could see me hurt, or if it just slipped out of her mouth accidentally all I can say now is that I may sometime in the future might forgive but I'll will never forget what she did.
