The best way to get rid of my mother's male friend?

My mother is too niave to realize that the guy is a snake. Hes been all around town chasing widows and married women. He only uses women for a ride. he doesnt have a car. he talks about her when she is not around. When my father died, he came over advertising himself and asking for another woman not my mother. He had no respect for the dead and grieving family. I tried sabotaging the phone but now he arrives. I need help if my mother still sees this *** I am leaving. I dont give a hoot where i go. I dont think i stand too muh more of this.
