My perception after watching the character over the course of multiple seasons, she doesn't strike me as someone whose overly concerned with the rules of society, or at least having them applied to her.
Whether to cheat on a spouse would be a personal decision based on her own rules, and Jadzia was shown to enjoy a carefree personal lifestyle. Cheating would be no big thing to her.
Again, my perception.
Funny cause I got the exact opposite impression, impulsive yes, but disloyal to that extent? I hope not, to be frank she kinda reminds me of my wife from time to time.
ah shit.....
