I think a deal breaker right now would be a continued affair. But, a big but at that is I think I can put the book on the back burner for a while and wait for trust to improve. I know there was an EA, but much after that I don't have any ideas or evidence to anything else besides the book comments.
I am reading a book on dealing with A, even has a cover blurb from MWD. I will see where the book takes me with new knowledge and coping skills contained within.
I never thought my W would remove the book from the house so if or when I decide to bring up the subject it will be a little different than just handing it to her.
Gogofo think about what the universe is telling you now:
You have trust issues.... You are not trusting your W, if you dont have any proof that she is lying or in an A why are you not trusting her?
At the end if she is having an A or not its her problem, and she is gonna have to deal with that.... I had told you this before, you guys are not together now so its not important for you to ask, its a way your trust issues are telling you: I was "right" I could not trust her......
My advice, work on your trust issues and develop strenght in that field, if she is in an affair, it would ended coming up and one day you will know, the way that you react that day will be different if you work on your trust issues....
The problem its not what she is doing, the problem is your flaw or not trusting, so far you have zero proof, once you are confident in yourself, the fact that she was in an A will not matter after what you went thrue, so thats my little advice...
If you confront her, she might dennied it maybe because its true or get upset because its not true and you dont trust her.... So its a lost lost game no matter what.
Hiwever, think about this, if she is in an A she might took the book because she realized she is doing something unfair and maybe she is fighting her way out of it to be able to give the new Gogofo what he deserves ( thats an option)
Let things die out of important by their own wait, dont interfere, the universe its taking care and as you told me many times....how will telling her something help you on the long term?
When the student its ready, the teacher will appear... Even after all this time the sun never says to the Earth, "You owe me." Look what happens with a love like that,It lights the whole sky.
