Should I delete all pictures of my ex?

No, look at them as a reminder of the mistake you made when ever you feel like you are going to make that mistake again.

Ask yourself the following questions; a) Was it a bad break up? b) Did your ex physically hurt you? c) Do you have happy memories of your own not involving your ex in some of the pictures? d) Does looking at the pictures cause you any form of emotional anxiety or depression? Depending on your answers to these questions, it would be a good idea to at first put the pictures in a place that is out of sight and mind. And you can reassess after a period of healing.

They are also your memories, and you shouldn't delete them just because your relationship is over. Unless they bother you and remind you of unhappy times.

Preferably yes. This is because pictures speaks a thousand words and you can trigger memories and sadness when you look at them.

I usually delete them. because in my opinion, an ex is an ex. There is no need to look back at your ex.

Keeping pictures of your ex, could result into deeper heartbreak. I would say delete the majority of them and leave about two of your favorites. Don't erase every good memory you had during the relationship. It'll help you grow.

You should absolutely do that if you don't want a relationship with him / her in the future.

it's probably best if you are ready to let go. keeping pictures will interfere with your process of moving on. you will always wonder and try to convince yourself that maybe it ended too soon. if you are sure you are ready to move on, delete the pictures.

No... keep 1 picture of him so that when u see that pic u realize that u r strong enough to let things go

Yes I did that it helped to not get tempted to revisit those days/memories back until I am sure I can deal with it
