Should I delete all pictures of my ex?

No you shouldn't because that's your memories of him and the pictures you have you should keep to show people when you tell story's about your exs

If it makes you feel better, then yes. It's a good idea if you are hoping to move on from the relationship.

This is a deeply personal choice, but one that I think people should avoid making in a hasty or emotional way. In our minds, we like to believe that things in our lives are permanent, safe, steady, and reliable, but the reality in the universe is that the only certainty is change. When we can accept that everything in life has a beginning and an end, then we can treasure the positive experiences that we do have, including memories with ex boyfriends or girlfriends! :)

Not every situation is the same. Ask yourself why you have them, and that should help you answer the question.

If you look at his picture and it gives you bad memories or makes you feel upset, then yes, you should.

If I was single, I wouldn't... but I'd be sure to keep them private. If I was in a new relationship I would, out of respect for my new partner.

If your memories of your ex are painful, I would delete the photos. If not, and you feel emotionally attached to them - then keep them. They could help you to move on. However, if you get a new partner you must expect some hurt feelings and suspicions if they stumble across these photos. It all depends on what stage you are at.

That's what I did, it helped me a huge amount, by doing that I didn't have anything physical that would remind me of them, it helped me get over them a lot quicker.

Honestly I would. They always say don't dwell on the past because it makes for a not so bright future. Although you my miss them you will always have memories. So the pictures are of no use. Keep your head up. The faster you move on the better you will be.

If you are NOT friends then yes. If you two are still talking to each other, then I don't you need to.
