I second Perna

You owe him nothing and his sickness this time is HIS problem. Not yours.

Not to say this is a good idea but it's a thought. I had a friend (actually a friend of my moms) whose husband beat her. She was not allowed to work so she bought the cheapest groceries she could buy and stashed the money in the cracks of the cupboards.

Pocket change from his pants, money laying around, change on the floor, anything.....scrape it up, stash it. AT LEAST if you make a run for it......you tried.

I cant even imagine what you go through on a daily basis. My thoughts and prayers are with you.
