A friend of 8 years stole a few dresses from me while we were out on a trip. They weren't necessarily expensive, just cute sundresses that I had bought after saving up some money with my first big job. After returning home, I texted her to get one back because it was the dress I wore on my first date with my (now) husband and was sentimental. I was willing to part with the other ones. Her response was "Since I already have it with me, it would be easier if I just keep it and not have to find a way to get it to you."

We lived ~20 minutes apart. After that, I was ghosted. She continued to wear the dress and post photos online, blocking me so that I couldn't see, but other friends saw and reported back to me. Safe to say she was not invited to the wedding.
