What do you do if your partner decides they just aren't going to even try to improve your situation?

I am so mad he's put me in this position where I have to make a choice between saving myself or saving him. He wont even try to help himself or us. I am so fucking overwhelmed and now I am just completely on my own and forced to make some really awful decisions. It's a lose lose situation.

Alright end of rant, I need to get out of this angry headspace as it's not helping my situation.
