I would have a talk with him. It sounds like you're saying he's not validating you're feelings.

I think it's important for our partners to hear us out without trying to "fix" our issues (being discussed) or "teach" us how to "look on the bright side". At the end of the day, he needs to be supportive to "you" and not every "D.ck and Harry" you're talking about.

I'm guessing he's unaware and thinks he's being supportive to you by being so positive about things. Talk with him.

On the flip side, if he's aware that you have Asperger's (from what I understand) who has difficulties understanding social cues, he could also be gaslighting you to think it's your condition (and not the other person) that's at "fault". It's a far stretch so, again, find out.
