Can I get unemployment if I quit?

I have been at my job for 2 years and about 8 months ago I got a new boss, we started seeing each other. I was a manager and while dating him I recieved 2 raises and amazing evuals. After a few arguements outside of work we slowly started to cut things off. A few weeks after a huge arguement at a night club I recieved my first write up at work by him, about a week later I was demoted (for having a bad attitude) I have gone out a few times with him since the demotion, after the dates I recieved new job privlages (like doing interviews for cash) then however I found out he was sexually harassing (via text) a good friend of mine and employee (she quit) now I hate even going to work. He does not even talk to me anymore but does make smug comments that I don't respond to. Can I collect unemployment if I quit? is there anything else I should do?
