You had a fight with Ghost about your past and you spoke out of anger and didn't control what you spoke anymore. As you wanted to walk away, he grabbed your wrist and stopped you

G: "Don't just walk away. Okay... I'm sorry, not everyone man you let into your life is a bad guy that you can't trust."

You: "Really, Ghost? What are you?"

G: "I am someone who shows up when you need me."

You: "I don't need you."

Ghost was hurt at your words. "Understood"

You: "Ghost, I-I'm sorry-"

G: "Don't apologize. I understood"

With that Ghost left.
