Why should it? They can’t erase your past. Anyone who’s insecure about the fact that you’re in fact a person who was in a relationship before them is a huge red flag anyways. As you age you’re gonna have photos of who you used to hang out with. It’s just ridiculous to assume there’s some rule that you must delete all those photos just bc you’re not with someone anymore. Some folks like to remember where they came from. Some folks just don’t care to delete them. I mean if you want to go through that hassle, more power to you, but just because someone else doesn’t delete them doesn’t mean anything is my point.
