What do you do with the reminders (things) from your past relationships?

With one long term relationship, we remained friends and I never bothered to put away the various cheesy gifts and reminders. Even now, they make me smile when I go home to my old room and see them.

With the most current breakup, I took it much harder. As a dramatic gesture, my most recent ex mailed me a huge box with all of the things that reminded me of him only a few days after the breakup. I added to the box and sent it home. (I’m away at school) When I came home for spring break, I was once again confronted with it and couldn’t decide what to do. Do I shove the box in the attic until the day when the contents no longer make me sad? Do I just throw it away? I don’t think we’ll ever get back together, but for some reason the idea of just throwing away things that were once so meaningful really tears me up. Do you think that keeping it signifies some subconscious desire for ‘us’ to someday get back together?

What have you done? Does the seriousness of the relationship and the conditions of the breakup make a difference in your decision?
