Did he ever feel something for me?

I met this boy a few months ago at school. We were taking classes after school and I really fell for him. I'll try to make a long story short:

We would meet every afternoon for our lessons. He's been gentle with me, always greeted me warmly. When we talked he would go quiet suddenly and just stared into my eyes. One time he invited me to his house to study together and the day after that we were walking together very close our hands almost touching. He told a friend of mine that he found me pretty and smart. We've been communicating through the summer and he told me about some personal problems he had (so that means he trusts me, right?). Last week he asked me out and we talked and all that just like before but nothing else happened.

I wanted to know if you think that maybe he feels something for me because he acts in that special way with me but he doesn't say nothing about it and I'm confused and suffering because I really love him but I think maybe he knows how I feel and he's just playing with me.
