I think you treat your husband appallingly to be honest, OP, and I am actually coming from a place where I want to help rather than be critical but in order to do so I have to be honest about what I feel, firstly about the situation itself and secondly about what I think the situation will evolve into.
You deliberately use quite emotive and strong language to describe things that are really no big deal in the scheme of things ‘I cannot stand dh smells’ as if he has fag breath, BO, halitosis - but it’s toast and coffee for breakfast. The rights and wrongs of that aren’t what I’m about here. What I’m saying is that there’s a difference between ‘d’you know babe, for some reason the smell of toast is really making me sick as a dog just now, I know it’s a pain but could you consider something else or maybe have it at work?’ and ‘Oh, I simply cannot BEAR the way you SMELL!’ The former is unlikely to get anyone’s back up but the second will.
Now we’ve got a TV standoff again. He was doing something normal, maybe it bothered you, maybe others think it would bother them, but from a relationship perspective what is important here is that there are few things more miserable than living with someone who tries to control your every movement, ‘points things out’ to you like a particularly critical parent, jumps on small things and then when you eventually get fed up and snap, twists it all round that they are right and you are wrong. In this case, ‘I’m pregnant.’
I don’t know what your long term plans are, OP, and it could be he’s a right bastard and you don’t know how to express it so are grouching about little things rather than subtle but awful abuse. But taking your threads at face value (and I don’t normally but it is relevant here, tbh) I am telling you now you will lose him.
What are your long term plans? Because I can foresee a future where he works long hours anyway and he works longer and longer because being at home is so bloody miserable. He has to tiptoe around because you make it clear it’s your home and it’s your child and he’s something of an unwelcome guest. He picks his child up for a cuddle and you won’t like it, he comes home late and greets you and SSH, he gets up early in the morning and wakes you up and he should keep a wash bag and change of clothes in the car ready to shower and change at work or the gym. And it can drag out for years, I’ve known it occur over whole decades until he meets someone who doesn’t think he’s an irritating shit invading their home and leaves. And it comes as a shock.
I’m not excusing cruel men, men who can’t keep it in their trousers, abusive men. But I would be utterly miserable living with you right now, OP.
