I think it sounds like a terrific relationship. If he's willing to go at your pace, what's the problem?
I also think you "feel" plenty, maybe just not the feelings you think you should be having. That was the case with me.
I would do what I now do with everything - give it time. Today I believe love grows, it is not instantaneous. In the meantime, I meet with my therapist and work on the feelings I didn't want to face, either.
He sounds like a lovely man - enjoy him while he's in your life.
