Who am i to him ( He is Capricorn )?

i didn't know where to start, i've been waiting for capricorn man for 2yrs, wild, party a lot and on a heart break from his 1st love. we rarely met as he is hundred of miles away from me. Last Christmas we met again and have sex for the 1st time, a few days later i asked him if he still want me to wait for him like he ask for 2yrs ago or just leave but he said he don't know. We rarely chat on facebook as he look continuously busy (with work & party all night long i guess) and sometime ignores me but i never complained or asking why. exactly a month ago he suddenly texting me and we talk a lot, but then he ask me if he can have sex with me again and i said if the only reason you want to meet me is for sex i guess forget about it and asking don't he miss me at all? and he said he does miss me and its not only for sex. A few days ago out of sudden text me again and says he want to see me that night, we met, bought a ticket for midnight movie, head to the beach b4 we watch the movie and have a looonnnggg talk and laugh a lot (he's so bubbly that night and looked extra happy when he saw his long lost friends at filling station) with very romantic and having fun, with me being laid back he looked comfortable, he nudge me a lot that night during movie (almost annoying)and we didn't have sex although he did ask for it but then he just said it's ok we dont have to do it tonight we will have another date next month, i realised that he changed a lot. Last night we have a chat and i take peep on his facebook profile and there's a few post from his male friend asking him to come over and have a drink & another post inviting him to a party but replies back "i repent, maybe we all should i don't want to have another party and getting sick of it". Is he really change? are we really dating (as that what he told to his friends at the station)? Am i just another friend and he is nice to me because he dont want to hurt my feeling? i realised that he glanced at me when im pretend im not looking. who am i to this guy? i dont want to beat around the bushes. Just in case this will help, i'm Sagittarius. Help me people, be as honest as you can.
