How much younger than Savi is Joss supposed to be? They just said Savi is 40, and surely they don't expect us to believe Joss is younger than 30. Harry and Savi were together 15 years, right? So even if Joss is 10 years younger than Savi, she would have still been in high school when Harry and Savi got married, so while young, not exactly a young child.
I don't know, I just like this story line and the characters. But, for one, it's fiction and I'm much more tolerant of things I wouldn't be in real life, and two, one of my favorite books is "Emma" by Austen, which this story line resembles, so I kind of love it. It's a stupid soap called "Mistresses", which pretty much implies improper relationships, practically the first scene was Savi cheating on her husband, and I don't personally see Joss and Harry getting together as somehow worse than all the other improper relationships on this show.
