I'm not going to completely remove ties to my ex from my apartment
Why won't you remove ties?
I do not want to go through cleaning his things after he has moved away.
You should move on and not associate with your ex anymore. They are your ex and they need to find somewhere else to live.
He has found his own place to live. It's that I don't want to move his crap.
Will he be there to pick his things up? If not then you are only doing yourself a disservice by having things that remind you of him lying around.
