Crazy ex boyfriend ans alcohol

Im a pregnant mom im due in Dec I have 3 kids already. Yesterday was terrible for me when my ex-bf came home in started being very aggressive towards after getting off from work. Obviously, he was fifthly drunk couldn't even stand up on his two feet cause he was that drunk. Mind you I have been up since 5 oclock in the morning cleaning, running errands, doing laundry and made food for the household. I was so disturbed in my sleep because he was very loud talking to his babymother on the phone in he was behind child support so she told him he can take his daughter no where until he pays something. He didnt have the money cause his been drinking his money all on alcohol so now after all that commotion he just came in attack me for no reason btw I was in bed asleep. Next thing it got very verbal with him calling me all types of names then one lead to another he got physical with me infront of my children it got very physical where he pushed me around my stomach even hit the crib a couple times in also I ran to the living run in he followed me in pushed me again to where I landed forward onto my daughters walker. Of course at that point I had to crawl to my kids room to call 911 for him he just would not leave so I showed the officers the videos I have recorded on my camera so they can see how physical it really got then they arrested him for battery charge. I eventually went to the hospital the baby is fine so are my kids.
