Stuck / semi - dependent on Mr. N for 6 more weeks. How to deal ?

I've written about my N recently. My situation is that I had things fall through and had to move in with him a few months ago. It was supposed to be temporary.
Anyway during the last few months I've come to see his true colors. A true 2 for 1 deal. Jekyll /Mr Hyde.

I was able to help him out with $$ for a while.
But he has insulted and beaten me down so much over recent weeks that Ive barely been able to get work done.

Half the time being nice to me and then WHAM telling me how I could be thinner, saner, more together, etc.

I have been forcing myself to get my gameplan together so I can start over on firm ground.
Looking at all possible finances I will be stuck here until July.
Which ironically would have been our 2nd anniversary dating.

I've tried to be very low key and pleasant when he in a nasty mood.
Part of me still loves him a lot, so it's torture staying here now. He is convinced that I WANT to be with him and think he will propose to me even when we both know he i miserable.

Anyway after cooking us a very nice home cooked steak and kidney pie dinner, he later told me he feels like Im a squatter here, that he is my babysitter (because I dont have a car and he drives me places) and then finally as we were in be falling asleep, he told me that he has kept himself from kicking me out on the street and that he "could be out having fun dating"

I don't want to be crushed but I feel so worn out and sick from his treatment of me.

How do I handle the fact that Im stuck here for a good 6-8 weeks ?
How to handle it and not crack up ?
Cause right now I want to run screaming down the street screaming from the horror of this untenable situation.
I now am sleeping on his coach until I leave.
