KlondikeJim,

I have followed your story because it has a lot of similiarities to mine. I implore you to not make the mistake that many on here do, and that is ending plan B too early and not setting the bar high enough.

She must enthusiastically agree to your conditions, and those conditions MUST include the following:

NC letter and NC for life - sounds like you have a pretty good start on this one
Complete transparancy - you said she changed all her cell number and canceled emails. Will she give you passwords and access to her cell and computere? If not, then its not transparency.
No more going out with "the girls".
Committment to MB's

If she tries to talk you out of any of these or compromise on them, then you should continue plan B and not let her back.

My WW would not agree to quit going out with the girls. We limped along at kind of a standoff about the issue for three weeks before I pulled the plug and went plan D. I went to one of her bars last week and now see the appeal. All she has to do is show a little cleavage, flip her hair a time or two, and the men come around and shower her with attention. It's filling an EN in the worst possible way and lead to OM#2 and OM#3.

It turns out that my WW wasn't necessarily addicted to any one OM, she was addicted to the single lifestyle and having constant attention from any men.

Set the bar high and don't compromise. This is your last good chance.
