What would anyone else do in my situation, help?

me and my ex boyfriend used to lived to gether but we got into a HUGE argument and it resulted in fighting and cussing and all. hes trying to put me out of our apt. but he is a big time drug dealer. im thinking about calling the cops and getting him arrested if he keeps trying to put me out my own apartment that got my name on the lease. so what do you guys think? should i get him arrested? becuase hes treating me like dirt. like we havent been with eachother for a year. someone give me some good advice.
