How can I tell what he wants? FWB or more? The story of how this all happened!

I've known this guy from my hometown since I was 16, I'm 22 now and I'm in my 4th of college, which is 2hrs away from my hometown, so I rarely get home. Since the day I met him he has flirted with me (kissing my neck, playing with my hair, hands around the waist, etc), but we never did anything about it because he's 3 years older than me (I was underage) and knows a lot of my friends and family (he's my cousins roommate), then I moved away for school. We still continued to flirt but we never seemed to be single at the same time, so we never did anything out of respect for our bf/gfs, even though it was there. We are now both single, and recently when I was home over the holidays he started talking to me more frequently on the phone, doing all the things I had mentioned before, asking me when I was coming home again. And when I was at the house and he was there, he left and came back and I had left , when he got back he was asking everyone where I went and if I was coming back. I came back to school from break thinking he was just upset because we hadn't seen each other in a while, but then he started texting me asking when he could come up to see me, which he has never done. I promised I would come back in a week, which I did. When I came back, he wasn't home but begged me to wait until he got back, when he came in I was asleep, he woke me up and we went into his room and slept, and we ended up having sex. Then I left and we didn't talk for a few weeks. My cousins told him I was coming back when I wasn't and he texted me saying he was upset with me because I didn't come by the house. So once again, I came home to see him. When I came back we hooked up again, and when we have, he sleeps with his arms around me, pulls me close to his chest and tells me to sleep in, we kiss goodbye and then that's that. But he constantly asks about me. My cousins have asked both of us what's going on and neither of us ever answers, and they always say things like "well its about time", "this should have happened a long time ago", and say they are happy for us, they see us flirt and all, but I don't know how to react to the situation. I've always liked him and this has me confused, I'm not sure what I want because when I graduate I'll be moving halfway across the country, and part of me feels like it won't work, but I want it to. I guess what I want to know is, since all of this is 6yrs in the making, and recently became physical, and going on how he reacts to things regarding me, does he just want a FWB relationship or something more? (Oh, he used to be quite a man whore, but with those girls he would make them leave right after...I've seen him do it. With me, he holds me for a long time afterwards) Can someone help me make sense of this so I can focus on school haha! Sorry the details were so long, I just wanted you to have to the whole story.

Oh sorry, he doesn't just hold me for a long time afterwards, he tells me he wants me to stay the night, he doesn't boot me like he did with the others. And my cousins say he hasn't brought anyone home since I was home for break.
