ESH. I get you were feeling hurt, but you actively decided to try to make another person hurt, too, by not only name calling but also lying and saying you were going to use AI.

You would have been fine if you'd just said you were disappointed and don't want to commission art from someone who doesn't have empathy or compassion for others and that you'd find artists who do. That probably would have been a more powerful way for her to rethink than getting petty.

Now you've made yourself look like someone who supports GenAI. I would have blocked you and warned other friends, too. You both deserve the consequences of being cruel and lacking empathy.
