((((((EG))))))) For your own sanity, try not to project too far into the future, with 'what ifs'. Just take good legal and DV advice and do what you think is best for you and the kids, step by step. Even write the steps down and concentrate, one at a time.
If you need a break from the calls and insanity, and you have good records, I'm sure the court will help you. Your AH may only be a few moves away from being institutionalised, and that could be the break he needs.
