You already know deep down what you need to do.
The children will suffer long term damage seeing this cycle over and over again. You the choice to decide what lessons you teach your children.
Lesson 1. You allow your partner to physically abuse you, allow the partner to return again and again and again. This lesson is saying to the children no matter how much someone hurts you it's okay. It's allowed because we don't question it.
Lesson 2. You stand up, you pack your bags, you stay with family or friends failing these routes, you call a women's domestic support service that will guide you and your children to safety. Will it be easy...no, will you have Independents, you and your children safe...yes. as their mother you have duty to protect them and protect yourself.
The fact this man isn't phased by authorities means this will get worse and worse as time goes on. Do you children have to witness their mother being assaulted? Beaten? Dead? ..... this is how it goes.
Do not Bury your head in the sand and thing that's not me...I'm not one of those women, this is the trap we all fall into and this is why we stay...we stay until we cannot take it anymore, the damage is to great, some of us don't make it out at all.
Do the right thing by you and your kids, get out whilst you can, pack, gather all the paperwork you need. Do what you need to do.
But do not stay, you are better than this.
If you could meet yourself now before you got married, could you honestly look yourself in the eye and say that you would marry this man...that you would allow this treatment around your children?
My words are blunt, I have been here myself, my life is so worlds apart from back then and I'm thankful I made it out and moved on. Do the right thing. I wish you all the luck you need xxx
