Don’t know what to do with our pictures together after breakup

As the title states I recently got out of my first long term relationship, I have 4 years worth of pictures of us together and I don’t know to do with them. Deleting them feels wrong because it feels like I would be erasing years worth of memories but seeing them in my camera roll is also weird. I’m just looking for advice on how people usually go on about this kind of thing.
