I wonder if you ever wondered why he would learn from you? Prove that he worships you. He thinks you are his role model. If you think he stole your thunder, and you are afraid of damaging your image and don't want to point out some of his behaviors, then with all due respect, your vanity is expanding! He has only one friend like you. If you are like others, you will regret your behavior in the future. Be more tolerant among friends. People who tell you to speak ill of you are also people who like to speak ill of you. Don't try to change others, it will make you very depressed! Don't run away, come on, you can handle the relationship with him!
