Hi Mary.
Um... hadn't you better sell the house? You won't be able to count on him making payments and then your credit will be just like his. Until you can do that... the police will be able to serve him if you call and say "he's here". As much as escape tempts you, if you can't afford the bills for two households you stay... he goes.... until the responsibility for the mortgage is LEGALLY not yours any more.
But I know how you feel. Sometimes we think we want peace at any cost. Look carefully at cost.
Hugs!
