Im so confused :( Should I just forget about him and move on? {detailed}?

Ok me and this guy only talked for two weeks then only dated for one. Usually I don't get hung up in a guy so fast but I guess he was easy to connect to and we spent a lot of time together. Then out of the blue he texted me saying that he didn't see it going anywhere and that he thought if we dated for a while and started doing stuff and we broke up, he didn't want me to think that he was just using me for sex (which really confused me because wouldn't he have to worry about that with every girl he dates??). Which in that week I let him finger me and I gave him a hj. I was just like whatever. Well then a week later he messaged me on Facebook saying that he missed me and he doesn't know what me needs and he asked me not to move on just yet because if he kept missing me the way he does he knows he should be with me and I just was like OK I'll be thinking to. After that we didn't text until a week later I caved in and said look I really need to know if you miss me or do I just need to move on..he said that he misses me a lot but he thinks we should just be friends then texted me asking if I was mad. I was but I said no but I wish you would have just told me that before and not gave me false hope like that, he said he was sorry and he didn't know. Then this weekend me and my friends went to a party and one of my friends said "I'm looking at brent right know" I didn't pay any attention until he came up to me and hugged me, he said he figured he'd come give me a hug and say hey..I just knotted my head...then about 20 minutes later I was watching my friends play beet pong and he tapped me on my shoulder asking me if I hated him, I said a little bit and turned around and walked away but he yelled at me to come back. I felt bad and a couple minutes later I went up to him and told him I was sorry, that I didn't really hate him and I have to tell myself that to get over him. I walked away before he could say anything. It pissed me off though when he would go up to my friend and started flirting with her and she didn't even notice till I told her so then after every time he came up to her she'd yell "f***!". Then after he party he texted me saying that one day I would realize how truly sorry he was and I said you don't want me and I understand that and he said you don't know how hard it was not to kiss you and I said don't say that your drunk and he said no I'm actually not. He also said that I'm a great girl and he doesn't know whats wrong with him..forgot the rest of the conversation because it was 3 o'clock in the morning and after we stopped texting I deleted it so I wouldn't be tempted to text him (I also deleted his number) then 2 days later he texted me asking if I got in a wreck because a few people heard that I did..and we haven't talked sense...I'm very confused I want to know what his deal is! It's killing me...
