Could my boyfriend have Asperger's?

ClassicReject
This doesn't mean i love him any less or am calling him out I'm just genuinely concerned about him and I was reading up about it and got curious so I'd appreciate the help.
-he takes melatonin to help him sleep and other things (I've never been told what else)
-has these appointments every Thursday night (he never tells me where, but if its weekly I assume therapy, I could be wrong)
-he can be very cold and unassuming at times
-lacks empathy or just refuses to show his feelings
-is rather socially awkward and loud
-monopolizes conversation
-is one of the most intelligent people I know
-often closes off into himself
-doesn't conform to social norms (which I love about him)
I don't mean this as offense to anyone, I just am repeating what I've read on the Internet.
weve been broken up a few months but he acts like he cares and says he doesn't. I just want to know why, especially because he never shared this with me and was going through some bad things at the time he dumped me. I'd appreciate the help :)
