the cat among the pigeons and look at the flip side. What do the exes think of you as an ex husband?

It take 2 to tango. I am on my 2nd marriage and try to be objective about relationships. As much as I can criticize my ex , I am sure she has words for me. Do you think that u changed much(if any) to be a better husband for your next wife? Do you think she changed after she left u?
The proof could be that if by the time you pass on to the next world, you have been married say 5 times, then there is something not right there! Conversely, if your ex gets married 5X in her life, then there is something wrong too!? Yes, No?
