Trying to leave abusive husband money saving tips

I’ve been married to him for 10 years we have two children aged 9+3

My husband has never worked and I’ve held my minimum wage job for the past 6 years taking care of my children myself

I depend on my husband financially because he pays the rent with his social security check $700. And I handle all other bills i’ve been trying to save money but it seems like things keep happening I have zero savings. Has anyone been through this I’m trying to get out soon. I’m desperate he fights with me In front of my children and it really effects them.
