Crying and just wow

So my baby is unsettled I go upstairs to say to OH who is in bed as comes in from work straight upstairs I had baby all day and now night I go up and say I can't cope he won't stop crying

OH looks mad I say fine il take him back downstairs

He screams at me to leave the baby I ignore and go down as baby due Feed

He screams at me we over

Smashes a hole in the living room door

Tells me to fuck off before he smashes my face in and nearly hits me I mean raises his fist I don't know if he would

Then calls me a slag and says he will kill my three children by ex partner

Then takes baby off me upstairs and tells me to stay away calls me a shit mother etc

I feel so lost I don't know anymore

I wish it would be over

He said we are finished he wants nothing more to do with me
