Boy problems

I have this guy friend and I'm highly attracted to him. Like would do anything for him. We was talking for about 5 months. He told me he didn't want a girlfriend at the time so we was just talking but he would get mad if dudes text me or talk to me. Now that we are friends he still gets mad when he see a text message from another boy. We have always had unprotected sex and we still do even though we are just friends. He comes over to see me frequently. My question is am I crazy or does it seem like he likes me too? Because he told me we should just be friends but we still have sex and he kisses me like never before. His friends thinks I'm stuck on him but I think he's the one stuck. I don't know what to about this situation.
