I would never use the word rebuild in the R again, this sounds like we are going to go back how things were. This is going to be all new, and never bring up the R to her, only if she starts to speak about it.
I remember a very real moment in my sitch when I realized I have said all I could say to her, I told her how I could not understand how she could do this to the kids, the family, me, how she has not thought this through at all, how she is selfish, yada yada yada. SO she knew how I felt, after that I had to change for myself, and if she liked what she saw, she would come back and eventually she did.
We are going out tonight for her birthday just the two of us and she told me she is even more excited to come home after dinner as the kids are spending the night out. 180's work, go back to just being friends and having fun together.
As far as the family goes, only my mother and father knew of our R problems and of course they took my side, and my wife knows that. She has been slowly building her relationship with them again and it is very hard but once, the initial meeting is over she saw that they were going to treat her like they always treated her, she is my wife.
