we are thinking about TTC
Please do not do this.
My ex-partner was like your husband and it was awful. It's frightening and abusive. If he can't manage his stress like a functional adult, without taking it out on you and making you feel like shit every time, he is going to be an appalling father. Seriously. If you have a baby, do you really want to be stuck in a house with a man who storms around the house slamming doors and shouting because of the stress when the baby won't stop screaming, instead of staying calm and trying to be supportive? Do you want to have a child who grows up scared of their father's angry moods every time something goes mildly wrong?
I didn't have kids with my ex, but I did see the impact of his behaviour on his son, and it wasn't good.
(Also, FWIW, eventually the slamming doors and storming around the house escalated into smashing things and eventually into domestic violence.)
Here's the thing: when something stressful happens, you need to be around someone who tries to make things better, not worse. It's bad enough when (eg) the boiler breaks down or your holiday gets cancelled or the house gets burgled or whatever - being around someone who adds that misery with their behaviour is the absolute pits.
Honestly, I would end this relationship. It would be awful to have a baby with him, properly awful. There's literally nothing more stressful than a baby, and he's going to make you and his child miserable.
