Yikes. I'm in California too and my aunt is married to my disabled uncle still and only reason she stays married to him is because she'll have to pay him spinal support if they divorce.
What I'm curious about, is why you would have to pay him spousal support if he's not unemployed at the time of your divorce finalizing. Why would you retroactively pay him spousal support? That part confuses me. Additionally, if he's unemployed and you're unemployed when he files (assuming that he's unemployed because you had to close your doors, which would effectively make you unemployed too) the courts can't force you into paying him since you'd have no income. I'd keep your savings because I can't see how you'd be held responsible for his well being after your divorce is finalized.
