No contributions to the household (rent, cleaning, utilities) and is verbally abusive. There is a grandchild involved. I've asked my child to leave often, then comes the apologies and promises to calm down, and life is calm for short periods of time. This has been going on for 5 years and is affecting my health. The home environment becomes toxic, and my grandchild is the mediator. This is not healthy for any of us. What can I do legally?
