I have often wondered what would happen if my W discovered I had read DR or see my postings here. My name is not my real name but I think there is enough detail in the posts that she would know it was me.
And I cannot help but think.... it wouldn't matter.
If our changes are to be believed they have to be long term. You cannot really fake that.
So even though she saw you had the book and may have even looked it up...and even though she said I hope you don't think we get back together... I think if she notices legitimate and authentic changes that that alone is enough.
