You mentioned that you had read the 180...
We still talk and can speak about the situation like two sane good friends.
but this is not 180. I suspect your WBF's life will only fill with more drama until he decides to fix his issues.
We often want things for our wayward spouses and significant others, but until they want to change there is nothing that can be done to help.
Something you might work on is why you feel very much love for a person who betrayed you, and you see as emotionally weak and pathetic.
