The fact that she knows I will be waiting while she test out the rest of the dating pool. Kind of like "I know your great and have made a lot of changes BUT what if there is something better" If I don't find anybody else I'll come back to you.
THIS IS PART OF THE CRISIS.
You are her safe person. She knows you love her.
They have to do this and I am so sorry to tell you this but most of us here have all gone through this part also.
Some call it cake-eating. Some call it being a doormat.
It may be easier if you try to look at it as though you are the light guiding her back home.
You are a sure thing.
There can be no testimony without a test. I am praying to go through this test and come out the other end with a new and better marriage then before.
