Yes, all the time. Most of the stories are over because i'm a spoiled dickhead, so it's not like having those things stored somewhere hurts or something.
I have a huge ass box full of pictures and things from my longest relationship, two years spent basically 24/24h with the only girl i've ever truly, deeply and madly loved. You always think you're in love but when it actually happens, it's a whole different planet. I'm now 100% certain you can only really love one time in life.
I would never get rid of it, my current gf, a literal angel and an overall much better person, found the box since we live togheter, but i managed to convince her it's important to keep it to remind me of previous mistakes, that having that box is the main reason i'm no longer a drug addict and a better person all around. But it was bullshit, i keep it to be reminded of how heaven feels like.
