Ask him to get a second job while you keep looking for one

Ask him to get a second job while you keep looking for one. And put in your application ANYWHERE - walmart, mcdonalds, at a hospital doing laundry, anything that's going to bring in money. Getting a minimum wage job still brings in 600-800 a month which will help out. Once you get your job he can quit his secondary if he still wants. But you sound like you guys desperately need the money so nows not a good time to be picky!
