i'm lucky enough to have pics of several ex's. all three girls were fine with me keeping them. i promised not to share them with anyone, and i have kept that promise. they are nice to go back and look at every once in a great while, and i never did until i was completely over them. just keep them to yourself (unless she's really smokin hot- if so, post away !
or not.) and never let your new g/f find them for crissakes!
