Sounds a bit like my ex husband. I eventually realised he was neuro diverse, in that he didn't look at the world the same way as me.
Have you considered this might be the case?
When we had my son everything was left to me, I had to sleep in a different room, so as not to disturb my husband, we were tolerated in the bedroom at weekends! (I realise now, as my son has sensory issues, that a new baby is sensory overload for a neuro diverse person). He could mask well, performed at work, but was too exhausted for my son and I once he came home from work.
We were intimate, but that was more down to, I think him thinking that's what he should do, what is expected of a husband. He would never spontaneously cuddle me, if, when we were next to each other in bed I tried to cuddle him he'd push me away (touching irritated him)
I believe he did love me in his own way, Part of me thinks if he could have acknowledged our differences (there were many more traits than just the sensory issues) we could have worked with them, but from the moment I tried to broach my 'theory' with him that may be he had neuro diverse traits, he was so affronted, he refused to acknowledge there was anything 'wrong' with our relationship, whereas I felt we were living parallel lives in the same house and I wasn't getting the relationship Id signed up for.
When we'd met he presented a version of himself he thought would be socially accaptable as a potential husband, he ticked a lot of boxes, but the minute he married me, the mask quickly slipped. Needless to say we split up, I am now with an amazing man, who supports me the way I need to and have an incredible relationship. My ex is with a girl who thinks along the same lines as him and now our son has the best of both worlds, a happy mum with an amazing step father and a dad who has now stepped up to his role as father (he needed the structure of being solely responsible for him on his set weekends) and as my son and him share similar traits he has a great time with his dad, whilst I don't have to live with his different ways and we all get along brilliantly.
