I started talking to a girl that has a boyfriend, I didn't think much of it just thought, hey two friends talking what can go wrong right? Well we both started to like each other a lot. She told me he boyfriend cheated on her and she doesn't always feel the love. She is just hanging on to the memories of them and doesn't want to let go. I haven't even hugged this girl only talked and hang out in person. She went out of state to go visit her boyfriend and I was under the impression that she is going to the end things but doesn't seem that way. So I told her that if she comes home single I'll do whatever it takes to make things work between us but if she stays with him I don't want to talk to her anymore. At times it felt like she was just using me to make her happen and she also said I give her a reason to live. I'm going crazy someone help me out. What should I do?
