When a Guy Uses Me For Sex?

[Fallen]

Lately I've been feeling very lonely because one reason I don't really have friends to talk to about things but the major reason is about this guy. This guy is just someone that I really have deep feelings for and is the only person that I really text. So without him texting me it gets extremely lonely because I don't talk to anyone else. What happened with him was that he was only interested in sex and he got what he wanted. I would have never had sex with him if it wasn't the only option because before we were friends. But when graduated from school, he didn't want to talk to me anymore and kept giving me all these excuses why he didn't want to be my friend. I fought hard to keep being able to be friends with him until finally he gave me this weird question "what would you do if you saw me in the shower." Then I new he wanted sex. I thought long and hard till finally I gave in and let him get his way because I wasn't ready to let him go. We've had sex four times and each time in between he ignores me for a couple of weeks or months until he wants it again. This has been going on for a little over two years and I'm not at a loss. I really always wanted to a good friend to him because he means a lot to me. Like hes the only person I can look up to and talk to. But he just doesn't want to and I never understood why he never liked me as a friend and why he just only wants this to be a sex thing. I really want to move on from this because its very painful to have a guy not want to be around you unless he wants sex. I really need help on what to do at this point and I want a better understand of why he only wants sex. So please help
