Need a little help...

So I live in a fifth wheel trailer with my "husband" (married, yes but doesnt feel lile it :/) and 2 kids (3yrs old and 1 month old) my husband likes to degrade me, make me feel guilty about things that I'm to tired to do and never helps me out and complains that we never have money (he spends it all on stupid shit and blames me and the kids :( we are falling behind on our trailer and car payments) but he doesnt want me to get a job bcuz he doesnt want our kids in daycare and bcuz he is a trucker so he makes to much for taxes. He doesnt want to go over the tax bracket :/ I'm so depressed I fear for myself and I fear my performance as a parent are going down Hill fast than I want :(

I would bbn like to see if anyone knows of any jobs that pay under the table (so he wont find out about it) so I can save up enough to leave soon and be happier?? Possibly at home to but doesnt matter.

Add - yes I know I need to leave BUT I cant bcuz I dont make money and he doesnt give me anything :/ I'm so desperate I'm at the point of possibly selling myself for extra money to save :(
