What happens when one of your very best friends hooks up with your...

you commit suicide

well first you confornt them both. Next you decide if one or both of them are worth the hassle of trying to repair the respective relationships. this may sound a bit sexist but my bet is you will dumb the girl and just mistrust the friend for a while. go luck that sucks but we have all been there at some point.

You mean after you broke up? If that's the case it happens. Its betrayal when you are together but when you are broken up its not. Even though we still think it is. The thing is your best friend could be a better match then you were. Wouldn't you want the best for the both of them? Its not about you anymore. You move on. No reason to dump your best friend over a girl.

You poor boy I had this happen. My friend liked more than friends he started going out with my other friend. It hurts so much to see them together.

Ha if one of my best friends did that, it would mean he was gay but never mind about that. I would never hang out with him again I mean it must hurt to hear him talk about her.
