Me and my friend had a fight over a game and now I feel like disowning him.
Does it relate to events in the past?
Yes, I was screwed because of her.
It sounds like this is about more that just PlayStation drama. You should try talking with your friend about what happened in the past that you're still upset about.
No thanks. I'm good at manipulating people.
I get that she annoyed you with what happened when playing on the PlayStation. But you should really consider if this is really that big of a deal to completely disown her. I recommend talking with her and letting her know how much it actually affected you, this could help you out in your friendship.
