Identity crisis

I'm 29, unemployed, broken shit. My mom attempted suicide because of my father's physical and mental torture when I was a kid, since then I grew hatred towards men but fell for a guy and continued that relationship for 8 years and 2015 I broke my leg and diagnosed with right ovarian cyst, so my boyfriend went on another relationship, so I left him and soon I started another relationship with my best friend and with times I discovered him cheating with so many girls. So now I'm trying to get rid of him but he's threatening me that he'll kill me if I marry someone else, though I'm not in any other relationship and now I can't even think of it as I went through more than my tolerance limit. Btw I've started my own business but couldn't continue because of my second boyfriend and now I'm struggling to get a job. I'm really tired and I don't know how to explain my situation
