I really agree with this. I went through a divorce and I have realized that sometimes in life all you get out of a broken relationship is a window into a part of your soul... you learn things about yourself that you didn't know before. Sometimes your heart aches so much because you long to have an opportunity to amend some of the wrongs you committed against the one you loved... "please give me one chance; I can change." But no amount of begging or pleading can create such an opportunity again when it's over.
I know it's tough to let go because in some respects, I haven't fully let go of my loss either. But I'm learning that accepting the loss is necessary to move on. I'm also learning that I have to face directly into the pain and see what I did wrong and try to learn from my mistakes. And I also think that in some respects I haven't fully learned all of my lessons yet. It's best to be on my own for now and learn and heal. Maybe you can take a page from my book.
I know it hurts my friend; believe me I do. But we all have to work through these hurts in life and move on and I hope you are able to.
Live well.
