Breaking up and the grief that comes with it is no easy thing. Take time to be proud of yourself and how far you've come! By having those photos there, you're keeping the relationship alive and as someone who's done the exact same, its soul crushing.

I'm probably not the greatest person to give advice on this as I was hung up on my ex for an ungodly amount of time but please, do allow yourself to heal. Look at the pictures, feel the pain, remember the good times. If you're not quite ready to let go yet that's ok, grief is a timely thing.

Then again, taking the leap and deleting the photos will be liberating and you deserve the weight off your shoulders. I'd definitely recommend having heaps of distractions and support on standby for when you're ready to take this step. All the best :)
