I really don't believe Elaine is the cheating type, plus John doesn't have the best track record. Even when he performs "Small Town" he blames himself. Anyway, I always thought John and Meg were odd together and sooner or later they realize that too. So all we can do is wish John the best.
I'm still a big fan and I look forward to John's new rock or not so rock album. I already preordered it so I'm just waiting. Best of luck!
