I had a friend who had a ex girlfriend that had a box with all his personal photographs he had taken over the years, and she refused to give them back out of spite.
I had similar except in my case she tore everything up into little bitty pieces and gave it back to me. Ha ha.
People get strange, no doubt.
Some people like the movie “War of The Roses”, but it hit too close to reality for me to find it entertaining.
When relationships go bad, it does bring out the worst in some people.
