Heartbreak changed her so drastically.
Before, she was unfailingly kind. Compassionate, affectionate, loyal. I want to say "sweet" but let's preface that by agreeing it's not a curse word. She brought something positive and good into her contacts with people.
After, she was bitter, arrogant, and controlling. She gave people orders and expected them to be carried out promptly. It's as if her experience of disillusion and failure left her terrified of loss of control. Her way or the highway.
You should be able to guess the impact that had on our relationship. I'm not good at receiving orders. There was a specific experience but that's not crucial because if it had never happened a different thing would.
She's free to be whatever person she chooses. For me, selfishly, it's a sad and confusing loss. To say that I loved her would be the understatement of a lifetime.
