Quoted: (((He "wasn't hurting anybody or doing anything wrong", he "didn't cheat or physically abuse me".
Well whoopty Do for him. He deserves a round of applause or a medal for NOT belting you up, for NOT cheating on you?
What does he deserve for bad mouthing you, when it was you keeping him, for drinking to drunkenness, for being too drunk or hungover to work, for not contributing cash or help into household? He gets what he got....told to take his gear and rack off.
NC is the way to go, no contact by phone, email, Facebook, letter, texting, and certainly no face to face. If turns up on the bludge for money again, tell him to stay away, not come again or Police will be called.
Now you can concentrate on caring for yourself.
God bless
