I've been dipping into and out of this thread but never posted but feel I want to now.
I think STBEXH could be on the spectrum. And by accepting that I am getting the answers I think I need.
He was very unempathetic. I'll never forget when my cousin died and I went to him (we weren't living together at the time) and told him. After an hour, he went to his mum and said "CatLady's cousin has died, but it's ok, Cat is fine now" I was and still am gutted to have lost my cousin.
He hated me receiving presents that he perceived to be of greater value than what he got even on my birthday and from my own family and friends. He'd complain and say "why do I never get anything nice/expensive". So I stopped showing him presents and lied to him when my granddad or my mum or my friends spontaneously bought me something. And if I ever spent any money on myself he'd moan about how we never spend any money on him (despite him having a PS+ Membership, Netflix (admittedly shared), expensive phone, and cigarettes every month while I tried to save money and not use it on myself).
He wouldn't let me have the wedding I wanted as he didn't want people to look at him.
He would only let me shop in one specific supermarket. Even if I bought the same brands, he wouldn't eat them if I'd bought them from a different supermarket because he didn't know whether he'd like the food bought from somewhere else.
He'd get angry. But say he didn't know why or what caused his issues, that he'd just see red and then he'd lose him temper and damage furniture. He did also hurt our DD twice and me at the very end.
And that's just the start. Since our split he still can't see how he was in the wrong, keeps telling other people that I'm stopping him seeing our DD (I'm not I just insist it needs to be supervised). At least I don't have to live with it anymore.
Oh that felt good. Very cathartic. I've told people in real life but they can't force him to go for a diagnosis. I don't want to seem like I'm slagging him off or I'm hateful of him, because I don't hate him at all, I actually feel quite sad for him if he is on the spectrum because it's not his fault and he is actually a really clever man and quite funny when you get to know him, he just struggles a lot with daily life I think.
