3 days NC! That's great Johne, you will see the dynamics change the longer it is, it has to!
Be patient and pray often!
I have been going through this for 1 year and 2 months. Recently I asked for the D since nothing was changing, I became her friend.. Not what I wanted if I had followed the rules.
I Should have been distant since the beginning.
Good luck my friend, you are doing it! Keep at it.
