Nope, Kitty, you're wrong. You never really let him go. YOU let yourself go. He's still there, in your heart, like he's always been. You just let him know. And that made all the difference in the world. You still love him. Ofcourse you do. Only it doesn't hurt you anymore that you do. And it doesn't hurt you anymore that he doesn't.
He knows now that you still love him. That you've always loved him. That you never stopped loving him. And now you feel better, because he knows.
And you know how he feels. Now.
You're free of the "what-if's" and the "could've-been's" and the "would've-been's".
And that's all that matters.
