Low income. Abuse

Hello everyone. I’m in abusive marriage with 2 little kids. I was stay at home mom all the time. And it has been 7 months I got a part time job. Since I don’t have job experience I have to go with minimum wages $9-$10/h. And I work 30hours/week and getting $1000. The one bedroom costs minimum $800-$900 without utilities. And I’m ready to leave him but can’t afford apartment and dont know where should I leave my kids while I’m at work. Any advice what should I do with apartment and daycare?
