Married 19yrs, selfish greedy minute man!

I can't work because he has ssi. If I did he would lose his money. So he's always all over me so I can't look for work. I'm so trying to look for work in hopes he will leave cause they will cut him. I have been taking care of kids for the last 19 yrs. I'm looking for a way out of this. Can't do it anymore. I want to take everything I have and the kids so I need to find the best way. And a job could help me alot. I haven't worked in over 10yrs.
