yes, echoing all the 'well done' comments, J
Take the next step for your own wellbeing, and don't call him or chat to him, giving him a 'chance' to show his feelings - I know there's part of you looking for a scrap of hope when you do that, but what you're hoping for - a loving husband again - simply doesn't exist, and as the phonecall shows you, it's just another chance for him to hurt you and display his contempt.
No contact. If he wants to talk to you about seeing the children, he can email you. Written contact only, then you have a record.
I think it is extremely likely he will try to punish you financially, for example by giving you a pittance to live on instead of 25% of his income - so make sure your solicitor is good and switched on about this. Can you access any of his payslips or bank statements? It sounds like an awful thing to do, I know, but I honestly do think that you need to become a lioness here, to ensure your children are provided for and that he can't punish you with money now you're out of the reach of his fists.
Also, however awful something like photocopying the contents of his desk might seem, remember it's not as awful as knocking someone unconscious and then telling them to get up and stop making a fuss. He's the sociopath in this scenario, you are the victim who's becoming a brave survivor.
So glad you posted again, DH and I both read your thread back in January and both worried about you, off and on. It sounds like you're doing wonderfully.
