My ex and I are still good friends after having broken up over a year ago, we are both weed smokers although I do smoke a bit more than her. I usually buy a larger quantity to get a better overall price and split it up to last accordingly. She asked me to sell her some, which I'll only do because she is a good friend. I told her that I'll give it to her at the same price I paid for it. She said she wanted a friend's rate to which I said that's the friend's rate is, no profit no loss. She argued that I should give her a better price and be willing to lose a little because we are good friends. I refused and said that's not how it works, it's not about the money(debating about 5$/10$) but the principal of the matter. Am I the Asshole?
