I am on a totally opposite side of things here, but I will second what Lucky said. I don't know of any man who wouldn't be hurt when their ex-wives or wives they left behind found someone else and was with someone else. Even if we don't want to be with you, the vast majority don't want you to be with someone else.
Meh... don't think so. If you move on--doesn't matter if you left or were left behind--you just don't care in that way anymore. Why begrudge somebody happiness if they really find it? And why ponder if it is real? Doesn't matter.
Now, if you have kids ... then you are more invested because if they make horrible decissions, it affects your kids.
