Before I was pregnant/during pregnancy, I used to do all the house work and his only job was to walk our dog which he didn’t like. There were some arguments but brushed under the carpet
This man must have a golden penis because why would you marry him? 😩 He gave you zero evidence that he had any intention of looking after his own house, once he'd coupled up with a woman.
he would threaten to rehome our dog
I'm careful with the word 'abuse', but this is abusive 100%. This would make me so angry.
That was his ace card to ensure that you would remain compliant and not get too big for your boots by actually advocating for yourself, for some fairness. It's cruel.
but the occasional play with our baby or cuddle when I ask him to and most of the time he would ask why or say I don’t want to (because he was watching tv or scrolling his phone)
He's a shit father too.
He does do a lot of the maintenance side of the house, such as painting the gate, gardening, etc. But he expects me to do most if not all the caring for our baby
He does the jobs he doesn't mind doing, that get him away from you and his child....and come on! How often does something need painting or even garden as opposed to washing dishes or similar tasks every day?
I find myself crying all the time during the day and night
No wonder.
You work full time, on top of being your baby's main carer, and you have a shit, selfish, unloving husband who threatens to give away your dog when you step out of line (as if he has the only say in this), and treats you as a domestic skivvy.
Don't quit your job. He will get worse.
