Why would my "boyfriend" tell me I'm his best friend but not love me?

Anonymous
I dated the most wonderful man for about a year. We are both in our 40s, and he was never married or even in a relationship with a woman before me. He is not gay, was just very very shy. We always have a great time together, and even though we never had sex, we did a lot of kissing, cuddling, etc. and he was always very happy to do so. He told me recently that I am his best friend, he still wants to do things with me, but he does not think we are right for each other romantically. That crushed me beyond belief. He still calls me and asks me to do things with him, go to dinner, etc. I am very confused. this person IS my best friend. He says he is not interested in anyone else right now. I am very pretty, smart, and treat him so well. So what am I dealing with here? Why does he still want to be with me but not have any physical closeness?

I should also say that I believe he perhaps has a high-functioning autistic disorder. I have told him this. His "equipment" works.even though we have not had intercourse, we have had other forms of intimacy.
