Thanks everyone, it was pretty much what I was telling myself, just needed to hear it from others. I'm going to back off, possibly still talk to him as friends, but not hang out or let it go any farther. BUT what if he does leave her and wants to give us a chance? Would it be wrong for me to do so? I'm not saying he will, I have no idea what he's planning on doing, but just something to consider I guess.
