What I might sugggest is looking at yourself a bit closer first. Are you sure it isn't your own insecurities that is making you doubt how he feels about you? Sometimes a "gut" feeling is really important in figuring out where things are going, but, if you have been hurt in the past, it is easy to jump to conclusions about how someone is.
I would say look at the way he treats you, anyone can say "Words' of love,etc,etc.. but, in the end, what matters is how they treat you. Is he interested in you life, does he try to help you along, does he care about you.
I am saying this because I am sort of on the other side. As a guy, the girl that I was dating got the sense that I wasn't too much into her. To be honest, I was sort of afraid because she seemed like such a great girl in many respects and I wasn't sure how close I wanted to get to her! But, she basically told me she wanted to back off things for a while and I said "okay' at the time. But, now that I have had time to reflect, I realize that I do want to give the relationship more of a chance (I was cautious with respect to moving things too fast, physically,etc... and I think that also got her thinking I wasn't attracted to her)
