I still have feelings for him! What should i do?

The guy i was seeing and i were not official or anything. We just hooked up and got to know each other. But then he said he had a problem with our age difference. (im 20 and hes 29) Well, after we "broke up", we didnt talk for awhile, but a few weeks later, we talked and decided to be friends. But the next time we hung out and everytime after that, we would have . Last time we hooked up, i was going through a lot of things, and i freaked out on him. We blew up at each other and didnt talk for a week. We both appologized for everything, and became really good friends and texted all the time. But we didnt hang out until last night at a huge party where he was a dj for some of it. He was so drunk and so was i, and i pulled him in towards me and kissed him. He smiled and said "couldnt resist, could you?" So we made out a lot. And my roomate was running around flashing people for beer. And he says to her "everyone else gets to see them, why cant i?" I could tell he was joking but it still bugged me. And the fact that he mentioned that he wanted my roomate and i to makeout so he would get turned on and do us both. That really bugged me. Is it wrong for me to not want to share him. I mean, its not like hes mine or anything. I dont even know if he still has feelings for me. He was drunk when we made out. I just dont know how im supposed to react with this. help please!
