There's a simple rule for this that applies in most cases: don't.
If they're in a happy relationship that they want to last, trying to break them up will make none of you happy. Neither her, nor her current bf, nor you, because you can't get him out of her head 100% since she will always have her memories of and with him.
The only case where breaking up a couple is in my opinionacceptable is when their relationship is very loose anyway and when she herself is willing to leave him for you.
Only if you agreed to be friends, which doesn't always work.
The song is about a young girl that tells her boyfriend to "leave the pieces when you go." after they breakup.
You did not explain whether you wanted to get her to breakup with her boyfriend for your own gain or that you didn't feel her boyfriend was treating her well and you're just a friend and concerned about her. If you are a girl then perhaps you have an alterior motive? Leave well enough alone and even if you succeeded in breaking them up she would go onto someone else and if she ever found out it was you that was the cause of the breakup you'll be history. Even if she is not being treated well, you don't like the guy or you're a woman wanting her boyfriend you won't win!
You can't
Tell him straight up ! Girl, NEVER stay with a guy who cheats. If he does it once, he'll do it again.
You either do nothing, because you are just trying to get over the breakup, or, you can talk to someone about it because you have breakup anxiety.
she did not breakup with him he did
your friends boyfriend will breakup with your friend, and your friend will get mad at you.
well is this after a breakup or something? if it is, he is just trying to make you feel better by telling you that. If its not, he is ABOUT to breakup with you because no guy or girl shall say that unless they are thinking of leaving their partner. I hope its not either of that. Good luck ..
well there are two ways i handle it . FIND SOMEONE ELSE ! -or- play it cool it was only an hour !
Breakup with him? You deserve WAY better.
Is this a serious question? You breakup with him asap.
