OP,
Your children do not feel safe.
The waking up.in the middle of the night distressed is a clear sign of trauma.
I think you should take a deep breath and have a good hard think.
Then i would ask your husband to come with you out of the house..into the garden perhaps and explain to him that if he does not calm himself down...he needs to leave the house. Tell him you are prepared to call the police to have him removed.
You and your children are being abused.
Yours is an abusive home.
You have deeply traumatised children.
This will not fix itself.
If you separate your children will have 50% of peace and believe me the minute they can refuse to see him, they will.
You need to be strong.
He needs to see you be strong.
The police will support you if you call and tell them you and your children are scared of him and want him out of your house.
He will be shocked.
He will be angry.
Your marriage is over whether you want to admit it or not.
You can get him out and you can protect your children.
Reach out for support IRL from family and friends.
You are NOT alone.
Lots of women are in this situation.
