I would rather the person did not tell me why the relationship was over. When a family member decided to exclude me after our mother died I could handle it. When he decided he had to tell me why, then I was left with the memory of all of his hateful words which just made the chasm wider. It doesn't take long to realize a relationship is over; but having to forget a bad scene is just something else that I don't want or need. The same is true with a past friendship. Words just make for more regrets.
