Master Don Juan
Don't worry about it, I edited out some rather uncouth words that were directed at you after seeing your first apology (it came in while I was still typing). 
You paid for dinner. You drove. You said "whatever you want is fine" every single time. All the effort, no expectations.
And she left anyway — probably for a guy who makes her pick up the pizza.
Painful. Also predictable. Her mind quietly concludes that anything requiring zero effort from her is worth exactly zero. You became a free sample, and free samples get taken for granted.
The 22 Rules flip the dynamic. Small shifts that get her investing effort, money, and time in you — until SHE'S the one afraid of losing YOU.
