If you are going to bang his ex - girlfriend then he is not your friend, plain and simple. Its been said already, but if you value the friendship then don't, but if you dont give a f*ck then go for it. The question I would ask is this dude in my immediate crew. I have a bunch of dudes I have been hanging out with since elementary school through university, and each of us would take a bullet for the other. If anyone in this group banged another's ex it would be a big f*cking deal, and he would never play it down, and it would probably get violent.
But really, if this were a friend from school, or work, that I know I wont talk to in a few years then I would not give a f*ck and f*ck away
