Would you in your own opinion consider her a pretentious slut? I was just providing some perspective. But what hurts the most is her sleeping with my best friend cause I cannot get that disgusting image out of my head, I can never sleep. There are so many other people in the world, that you don't need to hook up with your friend's ex.
My best friend had sex with my ex.?
Seeing a married man? Once in a while we would just break the friend boundaries and have sex because we weren't having sex with anyone else. Let your friend know how you feel.
My ex girlfriend had sex with one of my "best friends." Your opinion wanted!
So my question is why would anyone ever do this? You don't need to ram it down her throat, but she needs to understand what this has done to you and your friendship. Sorry for you pain and the pain of feeling betrayed, You need to confront you best friend about this, just to make sure of the circumstances of their encounter and that it did indeed happen and why it happened.
