All the time my ex says stuff that proves hes an idiot and that I was, in fact, right...maybe not about every single thing, but most things.
for example...
We were standing together talking and he said, "Yes, my wife sent me a link about that"
"You're wife...?" I asked puzzled
"Oops!" he said. "I mean my mother, not my wife. I havent remarried or anything"
Needless to say I burst out laughing and said "SEE! I told you I was your mother while we were married; and now your mother is your wife!" He was not amused ;)
What has YOUR ex said to prove you were right or at the least make you insanely happy they are gone?
