My parents divorced in 1956. Before it was "popular". It turned out that neither of my parents were a prize. He married 3 more times. And they confused us because we never knew what game they were playing ("He just introduced Mom as his wife?!"). I have a video my son took when he visited my parents with his young family. They're sitting on a couch at my Dad's, chatting up a storm with my father saying things like "Baby, do you remember blah blah blah?" It gets worse but I won't bore you. lol
I feel very sorry for the damage that was done to you. Selfish people never seem to care their actions will scar other people. If it feels good, do it. The truth will win every time. It sometimes takes a very long time.
