General Autism Discussion

Hello All,
I don't know if you actually will be able to help me but over a month ago I met a guy who I like a lot and I suspect he may have ASperger's syndrome. He never had it diagnosed and never had any mental health consultation.
Why I think he may have Asperger's syndrome:
- he is very honest, he always answers honestly when I ask him something, he told me some of the stuff I will present here
- he doesn't like crowds
- he says he is melanholic sometimes
- sometimes he acts socially awkward
- he is organised and does not like changes
- once we were walking on the street in the evening and he thought that someone passing by may have a bomb and made us to go to the other side of the street (he said he heard some noice from their box (I did not hear anything and got worried he may actually be paranoid)
- he has great memory and works in robotic field
- he said he has some OCD behaviours but sometimes only
- some things he understands when I tell him
- he notices details
-he's 26...
