I would take the baby & go to my mum’s place like you said you could.
Then at least she can be around in spirit with Surrounded by her memories & you can get some time away to not feel like you’re on some countdown to having to service this disgusting selfish person ?
My brother had a baby recently & just cannot imagine him being this way, he is besotted with his son & treats my SIL like a queen
This is so far from acceptable thinking
I wonder what other possible red flags there were or clues that give a hint he could turn so nasty
As others have said abuse can ramp up in times of commitment - moving in, wedding, pregnancy etc
Basically when they feel really comfortable the ugly comes out
Am enraged on your behalf that not only have you had to face losing your mum but your sad excuse for a partner has let you down so badly.
This is not fair & not on.
I don’t know how you could ever forget this comment. It would always be in the back of my mind causing resentment to grow
