Sounds more like Abusive Shithead syndrome to me.
I also told him after the last time to bang on the door and tell me to hurry up if he thinks I'm being too long rather than storming off like that.
He doesn't get to dictate how long you spend in the shower. Who died and made him god?
I mean, if you were in there over an hhour or something that might be a bit different. But even then, non-abusive shitheads wwouldn't be banging on the door and insisting you do what they want at all times.
His behavior is controlling and you're so used to him being in control (and maybe even had some bad past experiences with family or exes?) that you think this is how the world/relationships work. It's not.
I have ASD traits, but I don't try and order people around and people don't kow-tow to me. This isn't his ASD IMHO- or maybe he's using it as a free pass to be a twat. Either way, not a good person to have as a husband.
my objection is to the use of "AS" in the title. It's not relevant. He's being an arse. Why bring up his disability?
@NotPersephone OP thinks she should be worried about him. That's why she mentioned it. That is clear from her post.
She hasn't entirely realized he's an arsehole, she thinks his behaving in these ways is something he can't help and she has to shape her life around.
