OK so you dont have enough money to find a place alone then its time to start looking for ads from people looking for a roommate.

Why bother sitting with her while she watches TV ? Go to sleep or surf the internet, apply for a new job in another country? Do anything that keeps you occupied and away from her.

You mention working from home is she there all day or does she work ? (sorry I cant remember) Are you able to put in more hours to increase your income? Or maybe take a second job for more income but also to just get away from her?

Your in a terrible situation of course .. I would think making a move to get away from her would be worth putting up with a roommate or a living situation your not real thrilled about ... It would be better than staying with her.

Take care
