I broke up with someone who was extremely immature (and self-centered). She refused to discuss the relationship when there were issues and did not want to talk to me when she had a feeling I was going to break up with her. So, we ended up never seeing each other again and all of the sweet parts of the relationship were left unspoken and as if the memories and respect for the connection/relationship we had were left on the side of the road. I felt it was very disrespectful.
Anyone have a better story?
