It doesn't surprise me that she left. She seemed to have the narrative she was happy with already, she was the victim, in her eyes at worst she loved too much and to her how could that be bad meanwhile he was the bad guy. He was no prize but when you refuse to take ownership of your part in any situation, you close the door on any chance for introspection and ultimately understanding and growth. When we didn't jump in full stop on her narrative it just seemed a matter of when before she'd abandon the forum but she went the step further. Maybe we're wrong about her and this was just a bad moment and she posted and it got away from her, but if it's not, and the apparent issues are in her character I hope she grows/matures as it's only going to hold her back from the happiness she wants. It's not easy work to face yourself in the mirror and be honest with yourself.
