You talked a lot, I don't have time to follow the debate (maybe it's better

)
I'll throw in my two cents:
brutally speaking : Viv is at the end of its "prime time", if she had led an ordinary life - these are the last moments for unlimited fun. Soon she will have to look for connoisseurs like Macron

I have been in a long-term relationship myself (20+), and I understand all the presented behaviors.
I'm not judging Hutch or Vivian - she's not a whore/slut (not yet), although I'm afraid it's Chris's intrigues will go in this direction.
as I wrote at the beginning - the day Hutch disappeared, was the first day of revenge (on Chris)
He probably saw more than one fallen woman (by Chris) , and he will do anything to save Viv (and maybe marriage) - however, he will be exposed to a real test of will, forgiveness and love (Yes, I know, I'm an unabashed romantic

). Without it we would have the usual fap-games
btw. In my country, there is a name Witold—I don't even want to check where it comes from...
