Plz anyone help me

Ok so ...where do I start ...me and my bf have been dating for almost a year our anniversary was gonna be this month and make it a year.... one day we were fighting about him going to school and getting a job and ...he was just getting mad at me and cussing at me on the phone and saying how maybe he should find a gf that cares about him and shit or that maybe I should find someone else ...he was saying he was going to text other girls and stuff all becuz I wanted him to go to school and make good grades and he starts cussing at me so I tell him it's over becuz I have put up with telling him to do this and do that and he's 19!?!

I go to sleep when I wake up he's here at my house in my room i live with my mom and sis ..and he was freaking out becuz I broke up with him and he asks to get back with me and im like did u text any girls or shit and he said yes ....he told me a girl named melinda I look at his phone and I see his friends name covered up for her ....and I start to think about that ...I'm like scanning through their convo and I see that he asked her out and he had been telling her about our relationship and how we're always fighting. That was a really bad day for me .. later on we got back together ...sorta like made up.

What I'm trying to ask is if I should be with him or not .... idk I can never make up my mind on anything I can't trust him though ... that's me and him.
