So angry

Yesterday we got into an arguement because of his frustration because his car had broke down. His mom came over to try to stop it.. because I was going to call the cops because he has broken my phone & put his hands on me. & I wanted to go but he would t let me leave at all... he then got very disrespectful, saying he would fuck my cousin( one time I found them talking ) , like what the fuck? so he then apologized and blah blah. Now tomorrow I get paid and he’s screaming he need helps with getting it fixed and I told him first thing first I’m getting a new phone. He thinks I’m trying to start by saying that? Like NO , you can’t have all these different plans with someone else money. I want to leave but don’t want to make it seem like I’m leaving because things in his life are going down but idk I’m fed up & just need support. He means me no good. I’m 19 , he’s 30. He has 5 kids & also 1 child he helped raised. I have no kids. I get accused of doing everything when I don’t do anything but work and school... I’m so tired of it all
