Should I delete our photos on Instagram?

Not too long ago my girlfriend and I broke up. It wasnít a bad break up but we both prefer not to talk to each other for the time being. Thereís a zero chance for us to get back together so Iím trying my best to move on now. Iím just not sure if I should delete all my photos with her on Instagram. There are photos of just us two while there are those with our friends as well. A part of me is telling me to let it be while another part of me is saying delete it all. I just feel bad because all the photos taken during our Ukraine ski trip has her on it. If I delete it I wouldnít have a souvenir from that vacation. What do I do? In case youíre wondering, she hasnít deleted her photos as far as I know. She didnít even change our nicknames on Messenger.
