A few years ago, I did an art trade with a friend.Today, I saw an acquaintance post pictures of her booth at a local shop. I was surprised to see my painting that I had given my friend was on sale at her booth. I messaged both the acquaintance and my friend asking what was up. I stated that I wasn’t comfortable with the painting being sold for profit and not even being credited for it. The acquaintance told me that it was my friend who was selling the painting and that they share the space. The friend said she wasn’t the one selling it, which feels sketchy to me. I suggested that we do a trade back and offered her the item that she had given me in exchange for my painting because I didn’t want it being sold. She told me I was being petty and overdramatic. I know that the painting was hers and she does have the right to do whatever she wants with it, but am I wrong for feeling betrayed? Am I the asshole?

edit to clarify a few things, what I’m upset about is that my friend is passing the painting off as her own work. I wouldn’t be upset if she had told me she was going to sell it and if she had it listed as my art, not hers.
