Relationships and AS

[Confuzzled]

First of all, I'd like to apologise for the subject matter. It's probably been posted about many times.

I've been dating a guy for just over 3 months, who has mild Asperger's. I'm 16 and he's 19. Now, I know a fair amount about the Autistic spectrum in general; my brother has ADHD, one of our friends has Asperger's and another one has full-blown autisim. They're all absolutely amazing, talented people.

So my problem isn't that I don't understand, because I've additionally put alot of reasearch into the syndrome myself, but that I'm in absolute despair. We've both been hurt alot in previous relationships (I'd came out of a pretty abusive relationship 2 months prior), and he's really affectionate and stuff. At the beginning I was like, "wow, this is amazing! I'm with a really attractive, pleasant guy, and he'll always be honest."...so I know, the honesty can get pretty annoying when you want to be told you don't look fat in something , but apart from that, I saw this relationship as a blessing. My problem is that I was an idiot and stereotyped before I really knew him. I'm now aware that Asperger's differs from person to person, and he lied about something fairly important, and now I'm just crying all the time. So, with that, I have a question to other people out there who have a relationship with someone who has AS; How do you maintain the relationship? I don't want to hurt him, because I care about him, but he always yells at me or cries if we argue and I happen to be critical or point out a habit that sorta irritates me. I'd like to defend him here, I really would, when it's perfectly fine for him to critise me profusely, lie to me and hurt me. Should be part and parcel of the symdrome. He usually tells me afterwards that he's totally aware of offending me when he does it. I probably just don't understand anything about it at all, do I? All I ever do now is cry, and it's only been 3 bloody months.
