Please help me and my children

My husband and I decided it was best for me to be a stay at home mother with our two smallest girls ... I’ve been a stay at home mother for almost two years now ... before that I was independent and paid for everything on my own...  me and him were on and off because he would always walk out on us but it never hit me because I was always able to handle the bills so I always took him back ...
well he abandoned us and I came to find out by the school that he never paid for their school tuition yet ... utilities weren’t paid for several months and the mortgage wasn’t paid ... he left us as if we never existed, he only paid the car payments and said  that his ring is off so he doesn’t have to pay “my bills” anymore... I have four little ones with absolutely no income and no family around to watch them while I work.. I have no money for daycare nothing. Our church had to help and pay our mortgage and utilities... I’ve never been this scared .. I’m a very prideful person but right now I know I need to ask for help. I’m not originally from this state and I worked so hard to purchase our home ... I don’t want to lose it and I need a vehicle to get them around ... once he doesn’t pay on it , it’s gone.  Please, I’m asking for help to pay the bills for a few months and purchase a cheap car...
