I JUST CANT ANYMORE

So my S/O is an asshole. I see it now. I don't know how I didn't before. I am the only one who works, The only one who cleans, I cook and when I don't i buy us food. I pay half of rent. I do everything I can to make him happy. So when I was around 14 my father started hitting me again. I ran away and got caught up in prostitution. My fiancee knows about all of this. I was unaware of him discussing my life with his freinds and family. I found texts with his bestfriend telling him about the Prostitution to which his friend replied, "you can't turn a whore into a housewife" He has hit me and poured drinks on me, locked me out of the house, called me a whore, a bitch. My heart is just broken and i cant do it anymore. I know I should leave but I have no where to go. The house is in both of our names. He threatens to change it. This is a guy I fell for and I really need to wake up
