I'm not saying she can't have, say, a spiritual epiphany, H4H, but your wife certainly sounds like a serial adulterer, or something very close to it.
And I see nothing from her that indicates that she's aware that she even has a problem.
The problem with a person like this is that they will ALWAYS find someone "better," someone "more exciting." Unless they can address the root causes of their unhappiness and dissatisfaction, you'll forever be looking over your shoulder, IMHO.
