Hello all.
Having read through only the least couple dozen pages, i get the impression that there may be another way to view Hutch than is expressed here. As far as i remember the first part, Hutch was a full day absent after whitnessing his wifes demeanor with his boss in the boss's house.
A full day to come to a decision for himself, yet even a conclusion for his wife. His conclusion might have been, that any way of interfering with his wife's inner transformation will ultimately lead to loosing her, as she seems to set long suppressed feelings free, feelings she needs to explore to become the person she really is instead of the person she believed she was.
His decision was perchance to endure all humiliation, jealousy, envy, desperation he has to go through, to give her the space she needs in the new situation until she has grown up (as in a deferred puberty) and found herself. And only then they can find out if the marriage can evolve or has to be terminated.
If that would be the case, Hutch is the only adult in this novella, and far stronger than for example Christian, who would never had the strength needed for that kind of humility, nor Vivian, who seems to be the weakest one in that triangle.
In other words: Hutch is not dominant, not narcisstic - he might be self-reliant enough to take a hit without retaliating. In the end he might say to her: "I know what you have done and i did not stop you, because you needed to go to Christian and learn about yourself. Now that you have found all you need about yourself, shall we stay together, grow as a couple and bond on a new level of sincerity?"
