Need answers please ASAP I will delete later

So my best friend is he best mother in the world she has been abused by her husband for 5 years and JUST left 2 hrs ago. They share 3 children together.

He left marks on her and choked her so hard her eyes have blood in them. She has wanted to leave since the day she found out she was pregnant but couldn’t as he threatened her and her family (not the kids) (I guess he threatened her sister brother Mom dad and grandparents)

The child has never witnessed abuse other than a couple verbal arguments to which she would beg her husband to go in the other room so they can’t witness.

Anyways, she called 911, and left. She was told she should’ve left sooner because that’s the children’s best interest. She doesn’t have money for a lawyer and she only stayed in fear she would lose her kids.

She lives in ny. Cops, cps, everyone is involved now and I’m sure they will be back today to talk to everyone. But do you think she’ll lose her children? She is bawling. She needs reassurance. She has NO MONEY. She wants a divorce. She is pressing charges. I’m not sure if they will take hem away and so I told her I’d ask glow. I know it’s the wrong room but please answer

Edit : she didn’t document anything. But she has proof of this occurrence obviously and shes already out. Because she didn’t document what happens? She lives in ny

Edit2: she also wants FULL custody because she strongly believes he may hurt them in the future. Would she get this?
