hutch is thinking by letting his wife enjoy better sex with another man that his wife will stay
I think the concern here in taking that approach will be Vivian's acclimation towards being more sexually intimate with Christian due to her getting that implied free pass from Hutch.
Eventually, she will become more comfortable in Chris's presence and as a result, it will be seen as '
business as usual' for her and Chris.
Hutch certainly does exhibit a lot of the qualities of what a stereotypical representation of a cuck would look like. Being submissive and a natural yes man sort of a person, not questioning Christian's directives or politely interjecting in conversations between Chris/Vivian when he knows deep down that Chris's behaviour towards his wife is not appropriate at all given that Hutch is Vivian's husband. As an example, when Chris gets too touchy/feely/gropy with Vivian right in front of Hutch, he is looking to fish for a reaction out of Hutch, and when Hutch doesn't so much as bat an eyelash at what Chris is doing to his wife right in front of his own eyes, then Chris got the green light to continue such behaviour in-front of Hutch without fearing for reprisal of any sort from the latter.
but I would not say that love and sex go hand in hand. Regardless, yes, allowing one's partner to have sex with another person does introduce risk of emotional attachment developing with others
In the initial stages of Vivian and Chris's interactions, we rarely see the former displaying any sort of genuine affection for Chris.
At-least not yet. It's moreso the case that Vivian is being strung along for the ride, but eventually it might be the case that Vivian will come to appreciate and like the attention/daringness that she comes to expect from Chris, that she had wanted Hutch to fulfill that role, but since Hutch is not quite in the position to reciprocate those feelings of domination/daringness, and their sex life appears to have grown stale over the years, she turns to Christian to compensate for that gap in their relationship between her and Hutch.
Over time, Vivian could continue to put up the charade that she is only doing this with Hutch's best interests in mind, but I think we can all safely agree that there is an unspoken ulterior motive as well to explain why Vivian is continuing the tit for tat between her and Christian and not outrightly leaving the relationship altogether.
