How can you be helped into leaving your abuser?.
He will never work on anything; in his head it's entirely your fault and not his. Abusive men always blame someone else, anyone else except their own self.
He wants to be in this relationship so you can do all the housework and look after the kids whilst you cook clean and clear up after him. He is too lazy to want to find another target to abuse and he has you still around to abuse and mistreat as he sees fit. Such men HATE women, ALL of them.
Abuse is NOT a relationship issue; it is about power and control and he wants absolute here over you. The only acceptable level of abuse in a relationship is none. Remember that always and that is a good lesson to teach your kids.
He has always been abusive and has furthermore ramped up the power and control against you over the years.
What do you want to teach your children about relationships and what are they learning here?.
You being a fixer here has really done you no favours at all and that has further played into his hands. Who taught you that very damaging lesson about relationships - it was one of your parents, most likely your mother. That lesson needs to be unlearnt through therapy for your own self.
There is nothing to work on here other than you making plans to free yourself and your kids from his abuse of you and in turn them. Do not think they have not noticed; they pick up on all the vibes here, both spoken and unspoken, and they all know something is badly wrong.
If one of your children as an adult told you that they were being treated like you are, what would your own advice be?.
When he is "nice" he is merely in the "nice" phase of the nice/nasty cycle of abuse which is a continuous one. You badly need the help of both Womens Aid and a firm of Solicitors to seek legal advice and from that a divorce. Your relationship really ended the first time he abused you.
