How are you feeling today OP?
Echoing what other posters have said, you do need to report this to the police. Him blaming his outburst on you is terrifying.
When my children were 8 months old and 2 years old their dad attacked me because I couldnt stop the baby crying, then toddler started crying because her dad was so angry
It wasnt the first time he had hurt me, or even the 50th, ( together 7 years )
I literally only left because my 2 year old tried to pick me up off the floor, crying and shaking she apologised to me, thinking it was her fault. I told her it wasnt her fault, I said sorry to her and promised she would never see anything like that again. And she hasnt
About 6 months ago ( shes 9 now ) I was holding her like a baby and she randomly, started speaking in great detail about the attack, even knowing what colour the couches were and that we had 2 prams in the front room. Holding her like a baby unlocked an awful awful memory for her that she had blocked out. I honestly had no idea she would remember
If you report it to the police, you can go to the council, explain and they will help you move. We were in a hostel for a few months, then temporary housing for a few years then got a private rent.
We moved 50 miles away and started a new life, he was convicted in court and court ordered him not to contact or communicate with me or any child of the family
He isnt going to change and this is just the start. I know it's scary, it is it's awful, but you need to dig deep, find your strength and Make plans to leave
You'll be okay and there is a beautiful peaceful life waiting for you and your children, you just need to be really brave and take that step x
