There is a phenomenon that I don't see discussed much, I don't even know if it has a clinical name....the extroverted, confident, people-loving person marries the staid, reserved, supposedly rock solid introvert. The staid person (sometimes) starts to undermine the more outgoing partner, deep-seated, burning jealousy at the partner's apparent ease with.....people. And, who can undermine a person more profoundly than the partner who knows exactly where to stick the verbal knife (so to speak), to embarrass the outgoing partner in public where they can't reply in kind. I call it verbal abuse, it can be practically unnoticed by the friends in the group, but it deeply affects the more outgoing person who is being nastily "reined in". I see CW as that type of person (if there is a "type") who deeply resented Shan'ann's ease with relationships (thus professional success, too). He was the "Come here and smile for the camera, Chris" guy.
I too am not the type of person who would willingly pose for all the smiley SM videos, and personal revelations for a world of FB viewers. CW may have REALLY resented being the appendage, the one occupying the place of the staid, reserved, supposed rock of the family. Unfortunately that "rock solid" bit can also be a mask for cowardice.
So in the end he rids himself of everything that ties him to that type of self and essentially kills himself and all of them to do it. Kills himself as he will, for the rest of his life, be free of the feeling he needs to perform, from this moment on he doesn't have to work, to be something he is not. He can just spend the rest of his life as the coward he is, at the expense of the people in the state.
