A broken relationship .. help me :(

The man who got me pregnant or should I say young man. He's 23... I'm 22... he has anger problems. He's never hurt me but he's broken his phone and likes to yell. But the most hurtful thing is his lack of support emotionally. He is controlling and likes to make things go his way.. when they don't I am "punished". By this is mean he leaves me home alone ( I don't drive... sadly). He leaves from 8 hours min to 30 hour max.. with me not knowing where or when.. it hurts me and I can't leave him... I need too. I am home all the time by myself crying, cleaning, and hurting.
