Idk what to do

My kids and I are homeless with no where to sleep but my car ! My so called husband was suppose to watch our kids to go to work and been telling me all day he would be here. When I ask him where he is because I had to go to work in an hour, he tells me toc all off that hes not going to make it !!! Because he is with his friends . Everything is closed and I am out of options now.I need to divorce this piece of shit who does that! He sleeps at his friends houses. No I dont otherwise I would have had a place to live by now.
