He is not ready to talk, and feels very alienated. Read what jimi and BoomBam are saying (they are explaining it a lot better than I can).

Wow, BoomBam, I thank you so much for that. You paint such a insightful image of the life of a person with ASD, I don't think I could explain it any better than that, that's exactly how I feel too. I'm so glad you say you've got a girlfriend (a partner in this lonely life), that's great. OK, it's long distance, but it's still great, and you say it's not going to be long distance for that much longer. Holding thumbs for you that all goes well for the 4 years, and then thereafter too.

I think maybe what I was saying above in my post was not clear, or maybe it's just me that feels that way. But, it's so confusing. I get alienated from people the whole time. Somehow, I know it was my fault, but for the life of me I cannot work out what it is I did wrong. I don't understand social dynamics, I can't work out what it is I said or did to make that person go away from me. And, sometimes that person is not angry either, which then makes no sense to me at all. They come back and then they are friendly with me! I am at that point so confused. Why do they ignore me for months like they are angry at me, and then when I see them again they are happy to see me? Some people again I say nothing and then they begin to ignore me since I "obviously" did something wrong. I don't know anymore .
