I think I had sex with my boyfriend's brother. Should I tell my boyfriend?

First, you have to tell your boyfriend...he'll find out sooner or later and it's best coming from you.

Ask his brother again what happened and see if the answer changes. He probably won't tell his brother out of fear, but that's not the point.

It's your boyfriend's call after that. He can stay or go. If he stays, get ready to put some serious work into the relationship and prove that the mistake will never happen again.

If he goes, try harder with the next one. Trust is key to any relationship and once it's lost, it's hard to get it back.

Sorry for your situation...and try not to drink so much at parties to avoid this in the future.

He will find out, if not now 10 years from now. If your will marry this man, he needs to know. If not, take your chances. Once he finds out, he will never trust you, or respect you again.

wow..you are S.O.L. i think that you should sit down with your boyfriend and tell him that you got wasted and that you dont really know what happened but this is what you think and tell him that you are sorry
