It's interesting to read this since you have nomadic in your name and I am a nomad too. I have moved 100's if not 1000's of times in my life. I am probably the person people think ghosted them.

But really, I cannot keep track. I am in my own head with my own thoughts and not in sync with most other people. I'm 59 now and maybe 25 years ago, a person I knew asked me how many people I kept up with from high school. None. I went to 6 of them and don't remember anyone from any of those schools except slightly if I try hard.

Most people I encounter are online. Here today, gone tomorrow. I would never dream of wondering why they came or went.

In person, I am only in the place for a short time, so I just enjoy the time with the people I meet where I meet them. I'm grateful for the time I have with them, but I know I will always move on.

I hope you wore the lady's shirt for years afterwards. Never would I ever care about such meaningless thing, much less harp on it. You are best off rid of her.
