So he also can’t keep a job and gets fired for poor behavior (perhaps he can’t stay sober for long and when is sober cannot behave). So you are a sole provider? Where and how does he find money to buy weed? Do you pay for it? Supply him with drug? Why? Your finances aren’t separated?

Oh please he can’t keep a job yet he is the one “giving it all” on the job and quits out of resentment. I have hard time believing it.

If you are a sole provider how is he going to live if you leave? You’d likely be asked to pay spousal support. Longer you stay more you’ll pay.
