Report the violence.
go to the GP and tell them.
You HAVE to do this. it could mean that you CAN get an occupation order and kick that sorry wanker out on HIS arse.
You can't stay like this.
I split from my abusive (kicking) ex when my DS was 5, he's coming up for 8 now. ALL of the insecurities and issues he had then are ALL gone now. We are so strong and happy. AF will tell you, she was one of the ones that supported me when I was first out.
It's been a long journey, but every single step has brought me to greater and greater happiness. I know hundreds of former DV victims that are no longer with their exes (I'm chair of a DV charity, do talks on occasion etc) NOT ONE of them ever regrets leaving/getting rid.
FWIW, men that kick are showing a level of disgust and misogyny that is OFF THE CHARTS btw. They are the most poisonous for females to have contact with.
Get legal advice, report the cowardly MoFo and kick HIM out of your life.
Men that abuse do so from a point of abject weakness, they are the lowest of the very low, so don't be afraid of him, because actually he is more afraid of YOU standing up to him, you leaving him alone and exposing HIM for the fuckup he is than you will ever know.
If you want to start fighting your corner, start using every insult, word-for-word back at him. The words he uses are meant to cripple you. They are the worst words he can think of to use against you, through panic, to keep you down. So whatever he is using against you, is what he hates/fears the most in himself.
2 women a week are killed by their partners. when kids are involved they are at risk of death too. tidies up loose ends. :( This man will never get any better, only worse.
Get him out of your lives and keep him as far away from you as possible as soon as possible.
I promise you, on everything that I have, that you will never, ever regret it.
