This is a tricky one to evaluate. He's already indicated that he has more than a friendship interest in you--at least that's the way I interpret what he said about dating. There are some people who are so caught up in their own minds that that is all they can see and they won't take any other answer than the one they've come up with in their own mind. I guess what I'm saying is that I am concerned because this could potentially backfire on you. There is a perception that people on the spectrum can't be manipulative. I disagree. I know myself that there have been times when I have put my pet obsessions ahead of other people, didn't know and didn't care about the harm I was doing to relationships with my family, with others, all I cared about was me, me, me and getting my own way. I was not only mindblind, I saw no reason to change.
If this guy is developing an obsession on you he may very well find ways to come between you and your boyfriend in a passive-aggressive manner, using his Asperger's as an excuse. Because there really is no way to tell on the outside what a person is capable of doing but refuses to do, and what they are truly incapable of doing. Some of us who are highly intelligent are aware of this, and are perfectly capable of exploiting this fact. Things like continuing to come around even though it irritates your boyfriend, let's say. Until things escalate into it's a "me or him" situation. I don't know that this is the case, but I'd be very careful, especially if he's indicated an interest in dating you.
