My ex of 5 years broke up with me a little over a year ago...I never spoke to her during that time...I do miss her but she never reached out so I guess she moved on

I still have cards she gave me but in a box stuffed away...should I just throw that out? This might sound hippy but I feel as if her energy is in that box and she can feel I haven’t moved on...but I want to

What do you think
