This sounds like the situation I have myself in right now. Me and this girl have feelings for each other but she has a boyfriend who is a jackass to her and I'm nothing but positive to her. She loves him and won't give him up but she sees a possible relationship between us. I'm telling ya, Bob, the best thing to do here is stay friends. Be real good friends with her so eventually when the guy pushes her over the edge and she splits with him you're there like you've always been.
