Sometimes you just have to leap, and you will be surprised at what comes your way. I've done it a few times in my life, where action was necessary but I was stalling because of all the obstacles (which turned out to be just in my head).
It sounds like "home" has become prison for you--and with a very unpleasant jail keeper. At this point, playing out the worst-case scenario, would living in a shelter temporarily be worse? I mean, REALLY worse? There are programs out there to help women in transition. Try calling some social service agencies (including domestic violence shelters--even if he doesn't physically abuse you, you are being subjected to mental, emotional, and financial abuse), and see if they can help you out. That's what they exist for. Some of them can help with employment assistance, too.
Hugs, I hate to think of anyone living the way you are.
