Hypatia

You can still get closure. You just have to redefine it a bit. It is possible to get closure without having any actual contact with the other person.

This is going to sound really silly, but it worked for me. I wrote a very long letter to someone once, and really poured my heart out. It was something like 9 pages long. And then I went outside and burnt it. As the smoke went up and away, I imagined all my words, my emotions, and everything else connected to the relationship being carried along with it. And then it was all gone.
