He told her that I was a joke.

I found that I am a bit like you said. I will regret my talkativeness in the future, but once I tell someone, I forget it. In fact, I feel that this habit is a natural personality problem. Tell me how I feel. I always feel that telling other friends about other people's anecdotes is to make a good relationship with that person and send him a signal that I have a better relationship with you than that person. What about you? If he also told you anecdotes about other friends, it means that he still regards you as a friend. Maybe he is stupid and speaks ill of others because he can't find interesting topics.
