What was going on with this guy?

I was at a social group for people with Asperger’s and I was sat at a table with the quieter Aspies. One man with Asperger’s who was cute, kept eyeing me, then when I looked at him, smiled and said hi, he said hi back, then trying to talk to him was like pulling teeth and he didn’t want to work with me in group activities. At the end of the group event, I was standing there, looking down and when I looked up, the guy was right in my face, close enough to kiss me. Just lurking there in front of me, silently. I said hi and then moved back and he continued to get in my space until I moved to the side, then he walked past and talked to a group of other people. What was that about? Was he too shy to talk to me, trying in his own way, or just decided he didn’t like my personality? Most likely? I’m really outgoing and he’s quiet.
