If you can't afford the higher rent, and there's no way to increase your income then I'd have to say, "no" and just try to hold off as long as possible until you can find something else. While you are still there, I'd tell the father you aren't comfortable with "counseling" his daughter because of the way the relationship started off and you'd really just like to be left alone and treated solely as a tenant.
You do need to get out of there though, so try to search harder and find another way...
