So I used to hangout with this guy a lot about 4 years ago. We were together all the time and people thought we were dating. He would often ask me if I would date him and i would say no. I liked him but I wasn't stupid I knew what kind of guy he was and I wasn't about to get my heart broken. So about a 2 years ago I stopped talking to him and he still tried to talk to me until I told him to leqve me alone. He did for a while and actually started dating someone else for a short time but even while he was with her he kept trying to talk to me. I did from time to time but never saw him. He broke up with that girl and started dating his ex from a long time ago again. And yet still he kept trying to hangout with me. I finally did and of course we hooked up. At this point he is still with that girl and he knows I'm aware of it and we go behind her back and hook up. They live together now but the night he got the apartment he called me and asked if I wanted to go over. We actually hungout and hooked up in their place before she even knew about it. I'm starting to get feelings for him again and I hate it. I don't know if he'd leave her for me and even if he did I don't even know if I'd trust him from just seein how he cheats on his gfs with me. One of that last times we hungout he just looked at me and said that he really did like me and asked how come I never gave him a chance to be his girlfriend. And even asked me then and there to be his Gf to which I replied that he was crazy and was already dating someone. Sometimes just when i think im over him and he Isnt gonna call me, he does. Should I just get out of this while I still can and cut him off completely or should I just take a risk and try and be with him?
