Werewolf Fate/Love System?

I usually manage to bury that tense moodlet from my male werewolf "cheating" on his fated mate with his husband. My only issue is that the female werewolf is best friends with both her fated mate and her fated mate's husband, so the game thinking any of the three should be tense is just plain wrong. I view them as a harmonic, close knit trio that nobody from outside can interfer with and I don't want the Fated Mate status go away.
