Discussion: Fancy and Fleur (Patreon)

I've hit a snag in my writing for The Lies that Kill Us. It can be tricky writing an affair, especially between cutesy ponies. If I can spoil the plot a little, what I've got so far is that Fleur has her affair with Blueblood as revenge against her husband, who has grown cold and distant and too caught up with business dealings and the flanks of younger mares. The gist of it is, the Canterlot elite culture has poisoned them both, they have fully bought into the selfishness and snobbery of the upper class, and have developed negative coping methods to stave off their boredom and misery. Neither Fleur nor Fancy come off as a saint here.

A happy ending happens (eventually), but I'm concerned people will read the wrong message, "Fancy cheated first, which is why it was okay that Fleur cheated". That's not what I'm trying to say at all, it's just a story about two people who make terrible decisions, then grow and choose to forgive each other. :/

Also, I'm concerned that people will object to my portrayal of Fancy as just as self-absorbed and greedy as the rest of the uppercrust (even though the show has depicted him being so).

So what do you all think? Should I keep the dual cheating thing in (Fancy has several one night stands with Canterlot mares and their house staff, Fleur has one, extended affair with Blueblood), or should I cut it? Would it be better if Fleur cheats in response to Fancy being away and their marriage being on the rocks? I don't know if that makes for a weaker motivation, though....

So! Your feedback would be greatly appreciated! And as lovely as those comments are, I'm not looking for "Whatever you feel is best, Lop!". Honest criticism is valued here, don't be afraid to tell me my story sucks and how it should be rewritten!
