I guess my answer is to go, but i’m afraid I will get no money at all what I’m owed.. and I worked for it so I deserve it.
Staying because you hope to get paid is called “throwing good money after bad money” (or, in your case, throwing good time after bad time). Do you have any reason (aside from hopeful thinking) to believe that things will get better and that you will actually get paid if you leave?
Leave, and drag him to bais din and/or secular court.
