I like a man with Asperger's Syndrome

I don't "crush" (I feel like such a kid saying that) on people usually, so I was extremely surprised when I began feeling such strong emotions for one specific man in particular. I am always thinking of him, and not in a lustful, desirous way... but in a true, fond, warmth, "love."

He has Asperger's Syndrome, except it seems mild and you really wouldn't notice or assume that by meeting him. He is somewhat quiet (but quite able to hold conversation), has strong interests (which we share in common), but has adapted much better and differs so much more than the obsessive, shy, peculiar, "momma's boy" types usually seen on TV.

I have done a lot of reading concerning AS, but I want to hear from people who have it/have experience with those whom have it. Everyone is unique and individual, I understand, though.

I'm not confident in the "flirting" field (or anything related)... and I don't think I want to do any traditional flirting. We don't live close by, either. Ideally, I just want us to grow closer without him feeling trapped, controlled, pressured, or suffocated.

Advice would be wonderful. Thank you.

Does anyone have tips on picking up signs that he may like me? (Or, reversed, dislikes me?)
