Human: I'm having a problem with a friend. How can I get him/her to stop doing something that is hurtful to me? Assistant: 
It sounds like your friend has been acting in a way that is causing you pain, and you'd like them to change their behavior. You could try expressing your feelings directly, such as by saying "I feel really hurt when you do X" or "I don't like it when you do Y." If that doesn't work, you might also want to ask for help from someone else who can be a better listener and give you advice on how to address the situation.
