Interesting about the families. My W doesn't want me or our kids talking to her family about any of this. She says they just can't comprehend what she's going through - i just think she doesn't want them knowing the truth about her behavior now. I think she believes they would be disappointed.
All in all time frame is pretty good for this site! How long did it take for you to feel trusting again?
About a month, as she dragged her feet on a couple of the transparency elements, but finally did them all. When she self-confessed her one backslide (re-contact with OM), and was truly contrite about it, that helped. And she's never backslid since (and yes, I do check!), and that has helped as well.
Exposing to her parents, and our adult daughters, was key for me. What her parents (esp. her mom) and our daughters (esp. our younger daughter) think about her is VERY important to her, and it was their disapproval that played a big part in her ending it.
