She sounds harsh, how truly awful for you Louise.
This would be my plan B, find a job ANY job and I would try to find some shared accommodation with somebody you could see yourself getting along with until you were back on your feet enough to get your own place.
You might be scared and unsure initially but just keep remembering your goal which is to have a happy peaceful life.
This is why I am such an advocate of woman staying in the workforce, I see constantly too many woman being stuck in awful situations as they have no choice. Feeling you have no choices is perhaps worst than the abuse.
The positive for you Louise is you have no small children so really you only need to worry about housing yourself ( not sure about your DD), just try to gather every bit of strength you can muster and leave him. Nothing is worth your mental health, nothing.
The world is your oyster girl just get out of there and take it.
