By dropping the rope you don't offer any more resistance to what she wants. She has nothing to pull against anymore. You give her her freedom to do as she wishes, which translates into an action based way of respecting her decision and choices, even if it hurts you to do it.
Yes, doing it blows. You really don't do yourself any favours by hanging on though. Just shows them you're not listening, facing up to reality, and in a sense pursuing them.
I went through the same thing. The stuff H. left behind was sitting here, like a bad odor for months. My DB coach recommended the same thing. So I packed up the stuff, put it in a storage locker, paid first month's rent and gave H the key,contract and security information. I could not pack and store his desk. I got rid of that 3 weeks ago as my children were using it as a "shrine".
