It may have dragged on for many more months though, if the lie hadn't come out. What I find really sad is that, two people who had loved each other so passionately at one time, could treat each other with such little human respect. My friend the victimized spouse, may never see me as a real friend, for a long time anyway. But I hope eventually they will. Right now there is too much pain and humiliation for them to deal with.
Avoidance is a common behavior among the walking wounded.
The liar and I are no longer friends. I can't tolerate people who mistreat other people like that. I don't want them to be a friend. A person who can treat someone they love like that, certainly won't treat me any better. So the moral of the story is be careful out there and be truthful.
