Need honest job advice - hate my job - starting new

I can’t stand my job. It’s toxic and negative. Everyone talks crap about each other, my boss and counterpart have some kind of bond where she can override anything I say and he will agree with it, even when I am right. I have heard co workers talking badly about me and laughing. My hours are terrible 11-8PM. And I only make about $2,000 a month.

I am taking my real estate state exam soon and if I pass I am already signed in with a brokerage. The owner said that he will create an itinerary for me to follow while working for him and if I follow it and work hard I will be successful eventually. He said that he would prefer I do not even have a part time job as he wants me fully focused.

I am trying to be smart about it. I am saving up 6 months worth of bills. I am giving myself till August as I already have some saved. I also have the support of my boyfriend who said that I don’t even need to save up and that he will support me.

I am just nervous about giving up something steady even though I don’t like my job. Am I going about it the right way? 6 months of bills and I even have a fund for “emergencies” and “random” even though it’s small. I am making sure I stock up on necessities. Again, my boyfriend has expressed that he would support me if I didn’t want to work at all, that’s just not what I want to do. I don’t want to be a burden on him so I want to help in this transition. I am not planning on becoming rich but I do plan on making at least what I am now. Any advice?
