"Closure" to me is more about our need to release ourselves from the attachment to a person, place, or thing. I compair it to forgiveness. I believe I can achieve this without becoming reinvolved with the person, place, or thing. I simply allow myself to detach.
That's very nicely put!
I think that's key, it's about dealing with your own feelings and take responsibility vs expecting someone from outside to help you.
It's very difficult for most people as we like to play the "blame game"!
