Search Results: hook up at a club

so basically this guy and I had been hooking up for a month or so. we'd watch movies, go to clubs, hang out at bars, etc. he'd often stay the night, but we agreed on keeping it casual as he didn't want anything more than a hook up. one time when we went to a club, he started dancing with other girls in front of me. the next morning, he asked me if he had been an asshole or if he had done anything to upset me. I told him he had been kind of mean, and he said we should talk about it. he said he wanted to figure out what we were doing and that he didn't want to hurt me or be that guy who was oblivious. later we decided to keep it as friends as he said he didn't want anything more than a hook up and it'd be better this way. the next week at a party, he came up to me and said hi and later he asked my friends where i was because he couldn't find me. then he offered to give me my coat because I said I was cold. so I'm really confused now, can someone tell me whats going on? does he just want to be friends or is he still interested?

I met this guy at a club... he wanted to kiss me/ was very tempted but I felt shy so we just exchanged numbers. I didn't go out with him right away cuz I was busy working full time at a hair salon. So we spoke and I couldn't make it cuz of work and a meeting so 3 weeks later I asked him to go out then he said " sorry u took way too long". He then blocks me off facebook.

Then we bumped into each other by chance at a seminar exactly a year later and he aproached me and we started talking and re-added each other on facebook -he unblocked me and wanted to see how I was doing, etc...

Then 5 months later, we started chatting again one day and then we met up that same day for a date. We started making out hardcore and he unbuttoned my Jean shorts and we ended up having great sex - there was an attraction from both our ends.

The following day I text him a Hapy Birthday then he responds with "hey I don't think I wanna see u again", and he was telling me to go to my guy friend and that he's hotter than him - he sounded pretty jealous of this guy whom was only a friend/ business partner of mine.
He also blocked me off of facebook once again... I don't get it... did he not trust me? Or did he just want a hook-up?

Now let's say he only wanted a hook-up, why was he so jealous of my friend and asuming that we had it going on?
