Been together 9 years and have dc 4. It's been shit for a while but he's reared up at me over a stone chip on the car door 
and after a massive slanging match in front of dc and him driving off with her has now come home and told me he's really moving out this time, which I'm kind of glad about but am also shitting myself about as I don't know what I'm going to do about money.
He started his own business about 4 years ago just after I had gone back to work part time after having D.C. And while he was building the business my salary along with benefits was our only income. We are now in a much better position D.C. Goes to preschool I private school and was intending for her to stay there. I gave up my job a year ago and am now employed through the business, paid a wage but don't actually do anything.
My problem is I did apply for schools locally just to see if we got a good one but we had to move out of the flat in that area at short notice and are now not in the catchment area for the school we were accepted into as I wanted to be closer to the private school. There is no way I will be able to afford to send her there now and if he has to pay maintenance and to live himself then I don't see the money coming from him either. Also I'm obviously out of a job and wasn't incredibly well paid when I did work so chances of earning good money aren't good. The new flat is also expensive and would be out of my price range as a single parent. Family are a 2.5 hour drive away and I really don't want to move back to that area, have also not really stayed in regular contact with them. I know he's not going to make this whole separation easy for me because he can be a bit of a bully. I don't know what to do or even where to start.
Comments from anyone who has been in this situation or can give me some advice would be very much appreciated.
