What was I to him, just a fling?

I met this guy a year ago through the internet. At first I wanted nothing to do with him because I wasn't sure. I had just gotten out of a long relationship. BUt he kept contacting me and we got to talking and we would talk for about 5-6 hrs a night. When I met him for the first time we drove around and talked about stuff and when I got back to his apartment we had a heavy make out session in my truck. He wanted me to come inside but I told him I couldn't I had to go home. Well every time he would ask me to come over I would make up some excuse as to why I couldn't. Mainly because I was very insecure about myself so he finally told me. Look I don't think anything is going to work out between us. You're always busy and I have needs that aren't being met. I umed he meant . I thought about it and decided I was going to go for it. So I called him one night and went over and we had amazing . Well a week after that someone in his family ped away and he called me to come over and we slept together again. We would still talk but we never saw each other again. Well Christmas of 09 he called and asked me to come over. I did and the wasn't good. All I could think about was what am I doing? What am I to him so I wasn't really up for it and after 3 hours we both stopped and he asked me if something was wrong. I just smiled and said I had a lot on my mind. Never letting him know what I was thinking though. We went our ways again and still keeping in contact, mainly me checking on him I guess you could say? Well recently he messaged me and and told me he's been thinking about the last time we fooled around. He has a girlfriend now so I wasn't thinking anything of it. But then he told me if I would come over? Maybe I should have said no but I really wanted to. I never stopped thinking about him. I had other encounters with other men but I can never keep him completely out of my head. So of course I went, we slept together and the was really good. Well he called me the next day saying he felt so bad for cheating on his girlfriend and then later confessed he wasn't happy in the relationship. Then the day before my birthday he Text and told me he broke up with her. I asked Why? And he said because I cheated with you twice and would have done it again. If she didn't mean enough to me to keep me from doing that how was a long term relationship suppose to work out? I told him I was sorry and I was but I was a little happy also. Well we kept talking but we never had again. We flirted a lot and text each other other he did invite me over a couple more times but I'd be busy. Then he told me he didn't think he'd be dating anyone for awhile and I told him I was dating another guy. Well then the day after my birthday he text me and told me his ex was coming over and they were going to try and work things out. Little crushing but I smiled and said I'm glad and good luck. I checked on him a couple of days later and he said They were gong to take a break. Well he never stopped flirting with me and never stopped asking me over. Well just last week he sends me a text and says My ex and I are getting back together--I don't think we should be talking to each other anymore. Take care. I simply said wow sad, but ok good luck and be safe. I have like 5 different ways of viewing this but wanted to hear from someone else. Please let me know what your thoughts all, but don't be too mean please. I'm just a confused girl who's a little hurt. The main thing I always kept drilling to him was that I wanted us to be friends, real friends in the end no matter what happened. But for him to tell me that? I understand the girlfriend not wanting him to talk to me but I can stay away from him sexually. It's him who always wants me. He's told me plently of times. I just don't know?
