Search Results: flirting while in a relationship

So, straight to the point I met this girl and we hit off instantly, I could tell she was attracted to me when we first saw each other. However, I put myself into this complicated friendship thing between us. Consequently, we would hang out very often for example I was always in her room till like 2am and we would just have a great time. Also, there were times were she comfortable to lay on , get close to me, and we pretty much broke the physical touch barrier also she would she would cry in front of where I would console her occasionally and she would do the same for me. And thats how things were, then one night we got pretty drunk together in her room and I made a move where I ended up kissing her and she kissed me back, but she stopped it because she said if keep going were gonna end up sleeping together. I ended up leaving that night because I respected her, then a few days pass by and she calls me drunk asking me to pick her up which I did and she kissed me, and flirted with me while I was driving. So, that was our thing in the beginning now she has a boyfriend, I stepped away from her when they started to get serious. I found out her boyfriend is insecure from her and well she is beautiful girl I can understand where he was coming from but I never felt insecure when I was around her. Her boyfriend knows about me, he gets jealous that I am older, doesn't know about kissing each other, and doesn't like her dressing super nice to see me when all we do is catch up with drinks. And I can see it in her eyes that she feels guilty/regrets pick him over me to be in a relationship. There is some tension when we see each other and when we see each other she's happier, laughing, she was excited when I told her my mom wanted her to come over to hang out, and nervous when she's around me I can tell from her body language. She doesn't get that dressed up for him because I do see them in public or doesn't look to happy either.

So, do I got a chance, from my perspective?
