Have you ever seen karma do it's thing?

Yes, I have seen karma do its thing. It has kicked my ex-fiance in the hard. We were together for over 2 yrs. He dumped me for a girl he got pregnant while we were engaged. He cheated on her too, after they were married. She dumped him to move in with a much older guy (20 years older). He is now alone and miserable. I am still married to the same wonderful man that i met after my ex left.
