What if i said the person who my best friend cheated on was my sister/brother? i'm sure that will kill on the "i want him/her" comments.
That's Arkansas. Utah is the place where your best friend marries both his current partner and the one he "cheated" with, thus solving everyone's problems... except maybe yours. *disclaimer: this only applies to rural southern Utah near the Arizona border. Not the rest of them.
The Truth doesn't always need to burn through the city streets, spill into countryside, and singe the waters edge. Nobody is perfect. I'd wait until I see a real pattern. Two or Three times. Then you tell because they both are headed down a bad path. But until then, give him advice and keep your ears open. Give him a chance to change.
If it is a sibling, blood comes first. Kick your best friend's ass. If not, I wouldn't rat him out. But, you should probably kick his ass anyway. At least that way when your friend reproaches you for not telling her, you can at least tell her you gave him an ass-kicking for the whole thing. It may even precipitate a revelation much sooner when the girlfriend starts asking why he got in a fight with his best friend. But then, I do think violence is the answer for everything.
If you are going to rat your best friend out, which I don't recommend, make sure you tell your best friend what you plan to do. Don't go behind the ol' back and do it that way. But regardless....you have to decide where your loyalty lies in this case.
you tell your best friend that he's gotta come clean - it's the only way to fix the situation - then they can resolve the issue, maybe stay together if it works out and he promises to not cheat again, or they can break up. either way, your best friend has confided in you, and you'd be an ******* to tell this chick what happened, because it would put your best friend in a very rough situation. your job is to be a best friend to your best friend, that means do what is best for him. she does need to find out - but she needs to find out from him that he cheated.
I can't stand cheaters. And I'd rather be thought of as being best friends with someone who doesn't do that sort of thing. I think I wouldn't straight up tell, though. Maybe hint at it or just try to get the cheated to be suspicious of some things.
Rule number one, never become too good of friends with the people your best friends date. I always kept my mouth shut at my good friends player ways.
Close, but try it with you as the cheater (you may have to change the facts a little to fit your own moral weaknesses). Follow the Golden Rule. What would you expect your best friend to do?
It depends on how much you value your relationship with the cheatee -- if you do, you tell; if you don't, keep quiet. As for the cheater , thats his/her bad for cheating. While you shouldn't necessarily be the arbiter in this situation, you do have knowledge of what happen, which in my opinion, obligates you to tell -- in the very least, it buys you a slice of the responsiblity.
what will the sybling think if they find out it happened...find out you knew...and know that you didn't tell him/her?
