He doesn't hit you because he loves you and is unable to show it in any other way; he hits you because he hates you - and he hates all women, not just you.
He doesn't have much time for men either and that's because he only has time for himself. In his eyes he can do no wrong; he's always right, his way is the only way, and he's contemptuous of others.
Because he can't relate to the the world around him, he created his own world and populated it with you and the dc. He sees you and the dc as his creations, his creatures. In effect, he's made himself your god and he's an angry, jealous, god who demands absolute obedience from his worshippers.
He's amoral. He doesn't have a conscience and he's incapable of feeling remorse. Any promises he may make to change will always be false. Within minutes of the words coming out of his mouth, he'll turn it back to a self-pitying rant because, in his mind, he's the one that's hard done by and you've done him wrong by leaving him.
If you were to go back to him he will make you suffer for your act of disobedience for the rest of your life and, as you've been told, you will lose your dc.
They'll go into care and, once full care orders have been obtained by ss, the younger ones will be put up for adoption. If this comes to pass, should continue to have more dc while living with this man they'll be taken away from you at birth.
Presumaby he's on bail for assaulting you? If he's been charged with assault the case will be heard in the Magistrates Court and you're best advised to resist any temptation to prevail on the police to drop the charge(s) because, as I've made clear on numerous occasions, this man poses a very serious risk to you. Once he comes to the realisation that he can no longer control you, he will be a danger to other vulnerable women.
Stop protecting him and start protecting yourself and the dc by speaking out about what he's done to you. Once you put the information 'out there' you'll be enabling the authorities to deal with him as he should have been dealt with many years ago.
If he were to get a prison sentence it will be no more than poetic justice, although it's unlikely to be as long as the sentence you served in his prison.
He's far from being the big man he thinks he is and the law is your only hope of having him cut down to size and rendered powerless to inflict any more damage on you or the dc.
