His former best friend has a healthy boundary to not associate with drug addicts /liars.
They are scared to death for my safety, the safety of my home, the safety of my vehicle, the safety of my money, and the safety of my expensive belongings.
I know I need him out of here so that he can hit rock bottom on his own without me or anyone else continuously coming to his rescue.
Let's reframe this into a boundary:
" I want him out of here because I value myself, my sanity, my home and my stuff." That's healthy thinking.
Your fiance is living his life as he chooses. Nothing you can say or do is going to cause him to change. You can't keep him clean or safe and he is potentially dangerous.
