Question: Am I "out of bounds" for requiring this? Has anyone else done this? And, if so, I am I humiliating him? How does asking the WAH to do this "fit" within DB'ing?
I don't think there is any "fair" and "unfair" when it comes to boundaries of personal integrity. Either they are something YOU need, in order to feel right about yourself, or they aren't.
Boundaries are like fears -- you can't legislate them, nor logic your way thru them.
If this is something YOU need in order to feel safe in the marriage, based on his prior adultery, I don't see anything wrong with it. However, if HE feels that it violates HIS personal integrity to DO it, then I can see where he would refuse.
