<human>: My GF of 4 months has nudes of her Ex who she dated for years, married, and divorced. She was showing me some pictures on her laptop after a day of photography. She had the files shown with medium icons, and as she was scrolling through the folder i saw a few nude pictures of her ex. and photos of her naked with her naked ex. This made me quite uncomfortable. I've had nudes of my exes in the past but when we broke up, they got deleted.  It bothers me that she keeps them. I don't like the idea of her revisiting those pictures to reminisce or oogle. It doesn't seem right to me that you'd keep nudes of your ex when you've moved on to another relationship.

Summarize the given text in a few sentences.
<bot>: Am I in the right in feeling like she should delete the nude photos of her ex? If so, how should I go about bringing it up since it's been a couple weeks since then?
