Scared & confused

I am lost & just beside myself. I was assaulted by my babys father early this morning over an argument that we had been having all day. My 7 & 3 year old were woken up by him throwing the TV off the wall & into their room. He destroyed my bed frame & threw my sectional pieces all over the living room. He hit me a few times & we ended up outside. I was screaming hoping someone would hear & call 911 but no one did. I tried to take off running & he caught up with me. He pushed me down the stairs leading to my apartment. Back inside he was throwing my bed frame pieces all in the living room & I feel like such a terrible mom but our front door was open & I bolted to my neighbors house beating on the door for them to answer. They called 911 & he was then carrying my bed outside. But as soon as he seen the cops coming around the corner he took off running. My kids were so scared. He had my phone & kept telling me he was gonna beat my ass as soon as he was done & I knew if I didnt get out of there it would be bad. They never found him but said because he destroyed my apartment it's a property damage charge & a felony assault charge & now dfs has to be involved because my kids were there. I am 23 weeks pregnant with his child & just lost. Like I cant understand it or why. & now I'll be raising another child alone. I am so scared of him when he's drinking which is no excuse but he had been drinking liquor & he's always mean when he does but usually just with words. I kept screaming at him that I was pregnant and he said I dont give a F*** & I swear all I wanted was for it to work and him be there when his first child was born. I just want to move past all of this & be okay but everything just happened so quickly. I am in so much pain I can barely walk. But I feel baby moving so that gives me hope.
