Need Help! Relationship in jeopardy! Psyche in jeopardy!

[EmperorFurter]

So I've been with this guy for about three to four months. For the most part things seem fine, we've never fought and spend ALOT of time together. Yet I feel as though it won't last and it's just a "settlement" on his part. It was only meant to be a hookup for me as well, I just wanted to lose my virginity, but he asked me and I thought why not. The first two weeks the sex was great, lots of foreplay, kissing, bj's, switching positions, grotesqueness, etc. But now its devolved into him just getting horny, pulling my pants down and screwing me until he comes and its over, like fifteen mins is the most it lasts whereas is lasted two hours before. We haven't made out since the first two weeks, except for a time when we had a little bj three way with HIS friend in which he made out with me but only to please his friend I think. I want to be kissed. I want to get a blow job. I want to cum inside for once. I want to feel wanted! Why for no reason has it stopped! Please any advice would help. Should I tell him how I feel? He says he "cares" a lot about me, when he talks about the future he involves me in it. But theres a part of me that just smells bullshit. I am really considering just getting my thrills from other guys and eventually finding someone better, who'll treat me like I'm an equal.
