If you've asked him to leave, then it seems you are willing to consider divorce or separation. So then if you don't want to do the leaving, why not get a court order to make him leave. File for divorce or separation, ask for custody and possession of the house and for child support. Even if he can't or won't pay it, it will accrue and will give you leverage in custody and other divorce matters. Parents are required to support their children, and if he's unemployed his support will be based on his unemployment check or imputed from minimum wage. It's also how the court gauges a parent's sense of responsibility toward their child.
