I think they both walk around like there are 1 million broken eggs
I think you are right. But Tim gets tired of walking on the eggs. He knows he is a good, loving man without doing that, but he feels he has to handle her gently until her confidence is built up. But I think she's happy with the way things are right now. And maybe for a long time.
To move forward a few eggshells may have to be broken.
Is the authentic Tim the one walking on the eggshells?
