Ok, the woman is a nutcase.... Nothing more to say. You are a lucky guy Rob. Remember my words when you hold a real nice woman in your hands that loves you trully and deeply.
Dont write her a letter. It would serve no purpose. She isnt able to understand or feel anything.
About the L, I just hope it wasn't arranged so in case you punched the new guy he would be used somehow. I would expect anything from her. Seriously. Keep your guard up. Love K
