Okay, I got around to reading it.
Here's what I see. She gave everything to you, her body, her mind, her soul and her heart. You didn't feel the same way and slowly but surely pushed her away from you.
Now that she's moved on, you've had a epiphany. My God, you actually love this woman. Or do you? Is it possible you only want her because she no longer wants you, she's found someone else?
Stop torturing her. You tortured here through your relationship, now you're torturing her when she's doing her best to move on.
Harshness time. You don't deserve her. You never did.
Remember, if you love something, set it free, if it comes back to you, then it's yours, if it doesn't, it never was.
You're only thinking about yourself, just like you did all through your relationship with her.
Think about her for a change. Let her go. Let her be happy.
As for you, No contact. Will you love again? Possibly, but first you have to stop thinking only about yourself.
