That thought has crossed my mind several times. But other than the constant accusations balanced against folks saying that "the one accusing is the one doing it," there's no real evidence. Some circumstantial stuff, but if I had accused her of it with nothing more, then it would have just caused more "chaos" in the household, and things were chaotic enough.
One thing the author of the article said that struck home was about the children of alcoholics not liking order and preferring chaos. I'll testify to that, based on my experience in being married to one for ten years.
No, it is best you didn't return the accusation. You may still discover the truth in time -- if you even care to. But psychological warfare is a much more satisfying revenge.
Mwahahahahahaha . . . Not that I've done it myself, mind you. ;)
