I used to believe no one could relate to my experiences with my ex-wife..:what you just described was her to the letter..I can understand being upset at one another, and wanting what she was entitled to, and I had no problem with that, but equal and amicable was never her objective. It's been just over a decade and she is still slandering me. I have my opinion about her, but I never voice it to people, I try to always make a positive statement like "well, I wish her all the best".
Life goes on, but she will always be miserable..people like that are never happy, and their misery is like the plague!
