Depressed?

This weekend I was really busy and tired I work , go to school and have a side business so I was just laying in bed , he left to go get food and came back and asked me was I okay I said yes just tired. He literally SNAPPED!! Disrespected me and threatened to hit me ( he has before ) , once he disrespected me he said how did I disrespect you? “ tell me how or I’m gonna knock you out “ kept saying it .. I was shaking , if I showed any emotions he would’ve just beat me.. So it leaves me every argument saying it’s okay and leaving it alone.. he was literally talking to himself entire getting him self more mad. He even bought up a girl name who I once caught him texting and FaceTiming during our relationship.. They have a past of having sex and she’s the reason why him and his kids mom of 10 years split because he started messing around with this girl who he mentioned other day. He disrespected me so bad saying I’m the worst person ever , he has never been with nobody like me before lol but when things are good I’m the best? So after this we got back cool , that same night he got so mad because he asked me to turn around in the bed I said give me a minute because we had just got inside like 30 seconds ago and was trynna catch my breath . He kept disrespecting me saying oh how he wish he would’ve never choose me ( Shit I WISH I WOULDVE NEVER GAVE HIM MY NUMBER ) , he kept saying shut up shut the fuck up , saying I shouldn’t be saying no to him 😹 , like wtf! I’m so ready to have courage to leave and he keeps saying how much he loves me , it goes out one ear to the other it’s bull shit!!
