I used to have a bunch on my phone, but it was weird to look at pictures of good times after it's over. It makes it harder to let go and I would send her pictures of us and my son said that she would get upset and it messes with our emotions so I just deleted them. I have some on a disk somewhere, but I don't look at them anymore.
Seems I am the odd one out as usual :P Yes, I do, I have several of several of my ex's - not that I had many but the ones I did have I still have pics of.. I even have a very revealing pic of my ex's new woman :P And of the woman that he cheated on me with before that :P Maybe it's bitchy of me but I showed it to several people I knew.. most said she looked like a man - lol no wonder I wasn't his type after all :P
Several pics of my s/o, some quite provocative. A couple of exes' avatars on my fb wall, because we're still friends (my wife is friends with them too, so it's all good).
