Wow OP this is like reading my life.
I'm in exactly the same place now that you were in Feb. In fact I think I was in this place in Feb and we've possibly lived identical years.
My husband is very similar to yours, defensive, selfish, always thinks he's right, stubborn, and can be so incredibly hurtful.
I would say the BIG pluses is A. how tidy, and good at doing the housework he is, and B. how he is as a father, he is brilliant, and as such my DS adores him.
My friends think I'm crazy to want to leave him, he seems the perfect husband from the outside. But on the inside, in our four walls, he is so difficult to talk to, compromise with, and I'm always left mentally drained and shrunken.
We have a plan to move house in 2023, and have spent this year scouting new locations. I've been the one that's wanted to move for years, we moved away from family in 2011 for his work, and I've hated it. Now with remote working we can move back to an area closer to family. But is it the right thing for our relationship, or will this kill us?
We too have been through a still birth. I understand how hard that is and how it never really leaves you as a mum. Its strange thinking how my DH reacted and handled that situation, he was my rock. Not how I would describe him now! Now it's more like he IS a rock and I'm crushed under him.
We started seeing a couples therapist in August. That has helped, but I feel we are at a precipice at the moment, it could swing either way. The therapy has highlighted that my DH has a mind that is what they call neuro-divergent or more specifically is autistic. I on the other hand, have a neurotypical mind. This is the route cause of all of our communication issues. It is really bizarre as all the traits that indicated to the therapist that he was autistic were the traits I feel in love with him for....Logical, deep, sensible, passionate and dedicated about his career, and a little lost and in need of guidance on social matters. Now I see all those traits in an opposite way....Logical = Unemotional, Deep = Lost in his mind, sensible = unspontaneous, passionate = obsessed, and he is no longer willing to be guided, in fact it is seen as an insult if I try.
I was when we started out, his emotional half, but I feel like I have been fired from that role.
I'm not sure how my story is going to end I've been so close to leaving him this year, I'm surprised I'm still here. Actually no I'm not, I know why I'm still here, for my DS. No matter how separation plays out, It will mean I see less of my DS and he sees less of his Dad.
Where are you now, how did the summer pan out?
