I do intend to move at some point, but at this moment I don't have the money, although I am looking into housing co-ops which I think would be the answer.
At the moment I am mulling over a lot of things and haven't made concrete decisions about anything, but definitely by the Summer I will have decided as DD4 is due to start school then and if I am moving I will do it prior to her starting and start her at the new place.
I wouldn't move back here if I did move, as courts favour stability and if I was moving back and forth, this would be grounds for him to take custody. When I move, it will be permanent, that's why I need to think and make the right choice.
But I agree, if I stay near him he will just carry on doing this. I've put up with it for 4 years so I know that.
