I'm so sorry this has happened to you. However what you do now will decide how this ends.
You can leave, protect yourself and your children. Yes it will be scary and uncertai but long term you will be so happy and so will your children. There is lots of support out there, contact your GP, your HV, even call social services, they will help you leave him. Also contact local womens aid, all these people can help you. You are not alone in this and this is something that many people go through, but can recover from in the future.
Children need a safe home and learn from what they see. Violence in the home means your children could grow up to be victims/perpetrators of abuse themselves, and can damage them in so many ways.
Everything can be sorted, the house, money etc.
If you stay, he will kill you. and possibly your children. Best outcome, if he dosent kill you, will be your children being taken into care.
But deep down, you know all this. You say you love him, but he dosen't love you. Violence has no place in love.
Leave for your children, if not for yourself
I wish you all the love in the world, and hope you can leave and start a new life.
