Help, idk what to do anymore with life

Im in an abusive marriage, i have 3 kids, 2, 1, and newborn. Im unemployed and have no car. My family will not help my kids and i, unless i get my husband in trouble, and get the divorce overwith. There is no shelter available for my kids and i, all taken, while the ones available wont accept us cause im not a resident of their county. Idk what to do anymore, but to stay w my abuser cause hes the only one helping the kids and i with a place to stay and food. But hes abusive and a cheater, sighhh... any ideas?

One time i was with my family, and they acted like theyre going to help me, and they acted supportive. But behind my back, theyre all group texting each other, calling me retarded, stupid, and that im just as worst as my abuser. I feel like i dont have anyone but him. Its so hard and no one understands me at all.
