And how do you think your children will feel if he murders you?
Do you know that they will spend the rest of their life blaming themself for not finding a way to save you!
What you need to hear op, is: stop being so selfish. Yes. Selfish. You are wallowing in self pity to your own detriment just as you always have. Being a martyr.
If you truly feel you failed as a mother, stop failing now. Pick your ass up and get the fuck away from a man who has abused your kids.
You know what the biggest kick to your children is - you staying with their abuser. Not the failure of the police, not your failure to protect them back then. Your failure right now.
Get some damn self respect and grow a pair.
Get out of there.
Speak with womens aid, the police, the council to see what you are entitled to and reach out to anyone who is good and will support you. But most of all, get a grip and move your ass.
^ This. Harsh words but I agree with every one of them
It's never too late OP (I am not going to refer to you as Stupid). There is help out there if you genuinely want it. Do right by your kids and leave him. If your son is now in his own property why can't you go to a refuge now. My daughter did and spent a year in a hostel type place with 3 v young children. Hardest year but also the best decision she ever made
