This is abuse. Plain and simple domestic abuse. Coercive control and emotional abuse. I bet if he's controlling little things like an extra 10mins on a phone then he's super controlling about money and decisions about the house.
Have you changed your behaviour because you are afraid of his reaction? Do you feel like you are walking on eggshells around him? This is domestic abuse, its not just being hit. Abusers justify their behaviour by creating reasons to blame the victim, they cannot take responsibility for their own behaviour. He's angry at you because you dared to shout back and question his ridiculous "rules". Bullies don't like being questioned. Or to put it really simply - HE can't be wrong so YOU must be.
Please, please, please get your children away from this man before he wrecks their mental health. Get them seen by your local domestic abuse service so they can have support to understand none of this was their fault. They will help them learn what is and isn't acceptable in a relationship and not make the same mistakes in their own.
You say you are done, so I presume you want to end the "relationship" and leave your abuser.
Get in touch with Universal Credit to see what you are entitled to, even if you have to continue to share a house for the moment.
Get in touch with Child Maintenance Service the minute you can. He will not be reasonable regarding maintenance. For some reason they always view it as money for the woman.
See you GP they can get on the list for support and food bank etc if needed.
Phone the Police if you feel threatened or if his behaviour is unreasonable.
There is lots of help out there, lots of organisations ready to get you away from him. How old are your children?
Your life will be amazing without him in it and your children will be eternally grateful to you for getting them away from him.
