I guess that's just another way of saying that she feels she knows me inside out and is so turned off by more of the same that she is willing to step out into the great unknown. This would be especially true if she questions me and who I am.
I really am at a loss for what I should do. I have a wife who questions my love for her. On one hand, I want to say/do something to communicate my love for her and how valuable I feel she is, on the other hand, I don't want to pressure her and cause her to feel that it's not love for her that I feel; it's a need for her.
