To me that isn't selfish. Selfish has a negative connotation. I'd say it's doing what you have to do to heal.
Or is it a way to leave the door open?
It could also be that she doesn't want to get her stuff as she doesn't want to interact and is wanting a clean break.
With things like this only time will tell.
I'd say it's about a 50/50 chance both ways. As far as a clean break is concerned, she hasn't erased her "paper trail" of me on Facebook, and she even has a photo of us together still on her main page. It's been 2 months. That's not a clean break I guess. Unfortunately, this action sways my thinking to the "open door" theory.
And yes... .only time will tell.
