In the age of social media, we all have photos of our ex-es. What is the red pill way of dealing with this?

To be honest I wasn't too happy to see LTR hadn't taken down her ex photos on her IG page. I assumed it was etiquette to do so.

I can ask her to delete it, but how should I go about doing so? Is it just me being insecure or is this a red flag? These photos are from 2014, and she told me she broke up with him because he was too boring.

PS. Took her v-card so this ex didn't have sex with her. She gave him head though.

Edit: when I found out (she was showing me her old photos) I just said 'oh, your ex?' before scrolling to other photos. Good/bad?
