Boyfriend?

"So, there's this guy..." Isn't that how all good relationship questions begin? Well, there is. And I'm not really sure what to do about him. I can usually tell when someone likes me, but this particular John Doe is dificult. He helps me any time I need and takes good care of my car, but I'm pretty sure he does that with everyone. He also opens doors for me, and walks me to my car at the end of a night of hanging out--both things I've never seen him do for anyone else...but I dont know if he does it just because I told him to way back when I met him. If I make the effort, we'd see each other several times a week, but when I wait for his call, it seldom comes. So, here's my question: Does he like me? Or am I just vain?
