DP and I own a small flat which we live in with our two children, aged five and eight months. We are unmarried. We both work full time, but as my work is more flexible, I tend to do more of the drop offs and pick ups and holiday care (which in practice means that I have to catch up with work evenings and weekends and work suffers for it). He frequently works away from home, meaning that I am often solely responsible for the children during the working week.
If I leave him, am I likely to be able to stay in the property with our children, or are we going to have to sell up, split the equity and find separate properties? I am unlikely to be given a mortgage on my own as my work is done on a series of short fixed term contracts - I'm worried that the instability of my work might mean that I can't even rent a flat. We are in London so accommodation is silly money, whether renting or buying, and to move out of the city would mean moving away from work, support networks, daughter's school etc. DP earns good money (higher tax bracket) and unfortunately I earn very little (due to the nature of our industries - I can't really get around this by working harder / getting more qualification etc).
