Discard belongings too?

It’s me again! Don’t worry, I won’t spiral into questioning the unknown on this post. However, I do keep having random questions pop up and I just wonder if you all have any insight. See previous posts, but my ex moved home out of the blue after a hospitalization and took maybe a third of her things. She told me to trash the rest. Since I’m now responsible for getting rid of what she left, I’ve been going through it and some of the little things she left shock me. She said she didn’t have room for most of it, but for example I just found a pile of old DVDs she left. I always thought it was dumb that she loved DVDs so much because of streaming but she always SWORE by them. Wouldn’t let me touch them. For those of you who were discarded, did your SO discard their belongings too? Most of the things she left she brought into the relationship. Only thing of sentimental value I saw her take was a guitar.

ETA: the bulk of what she took was clothes, surprisingly even clothes of mine that I had given her.
