How does an autistic person act when they like someone?

I'm 20 and he's 21. I suspect he has autism or some sort of social disorder because he kind of shows most of the symptoms. But that doesn't matter to me. Anyway, whenever I talk to him he gets nervous. Once when I hugged him he got nervous. I would catch him staring at me. Sometimes when I talked to him he would come across as standoffish. There were even times when I would greet him and he would say "hi" sadly. When he'd be with his friends and we would make eye contact he would quickly look away and pretend I'm not there. When he's studying he acts cold towards me but I guess that's because he's busy. I sometimes feel like he doesn't like me. Then I get the feeling he likes me because he gave me his number when I asked for it and approached me first that day.

As I said, I got his number. Sometimes when I text him he doesn't reply and other times he does. When I attempted to talk over the phone with him he claimed that he was busy. So far I've initiated contact with him. Any advice on what I should do? Should I just tell him I like him?

He also laughs nervously when he talks to me or acts odd.


The very first few times I spoke to him, he used to walk away from me in the middle of a conversation. I realized that he didn't know what he did was rude.
