Salalex, this is awful. I read this with much sadness. It sounds like your husband saw your 'crime' as the excuse he needed to explode. If it hadn't been that, it would have been something else. I sounds like anything you do, even telling him you are going to clean the house for the valuers, is going to get a s* response.
I am glad for your sake that he is going away for a while. It sounds like you need the mental space to make good decisions. Having a bully at your throat is not condusive to clear thinking. Hope you get lots of advice from the solicitor and anyone else who can help. While I, too have concerns about him possibly trying to say you've abandoned the children, your solicitor should help you through this.
At least your daughters will not be witnessing the visits to the solicitor, valuations of the house and other meetings that could upset them.
I have no experience of this, but I really think you need to get someone - police, solictor, doctor - to look at your injuries and record them asap. I imagine this could be of great importance when divorce proceedings begin.
In our area, hopefully yours, too, you can phone the police and get put through to a section dealing with domestic violence. You do not have to give your name or address, I believe, so you do not have to oficially report the incident. Specially trained officers will advise you on all aspects and can also put you in touch with solicitors who deal in domestic violence and divorce.
I am sure you'll get tons of support here on mumnset - at least with your partner away, you can post when you want to. But, don't like to say this, but does he know your nickname? Is he likely to look on the site - or don't you care?
Thinking of you. Remember - you're strong, he's not. Keep repeating as necesssary.
