Okay, I understand. You have a solicitors appt this week, right? Can you have the solictor write him a letter outlining the new rules?
He sees you as a victim - his victim - and he's running rampant all over you. You need a third party to intervene, I believe. Is there anywhere you could go for a week while he is served with papers? Or someone who could take the kids for a few days?
There just has to be someone who can help you. If the solicitor can't write the letter, can you not just go to the police and tell them you need some help? You need someone to come to the house and explain that he cannot touch your things, your car, etc. Perhaps, and this might be dangerous, you really should put locks on your things. It will piss him off but if he gets violent again, it will move your case forward? You have every right and in fact a duty to abide by the law with regard to your benefits, so this would not be unreasonable behavior on your part.
Otherwise, what happens if you just start to say No? NO you can't take my car or I will call the police. NO you can't have my biscuits, NO i'm not making you tea. NO NO NO I want a divorce and that is FINAL.
Is that too scary to contemplate?
Last, sweetheart, is there anyway he can find what you write about here? After seeing what just happened to MLS, I'm concerned for several of you.
