But you did in fact give him a chance already.

Here are two different scenarios. Which appeals to you better? Or, better yet, after looking at these two scenarios, describe the scenario that you want to see in your life with regard to him.

1. You tried to be friends with him and now you dread hearing from him. You don't want to be in touch with him at all anymore. It is time for him to try other people.

2. You are willing to be friends, but not in a relationship and not as a de facto therapist. You tell him that and see how he responds.
