It tells me that she's on some bullshyt. But In my experience I've had a woman return the favor for the dates I take her on. I've even had her invite me to a place that I didn't have to pay for anything and she covered it all. But for the most part I just prefer to pay.
So out of all the women you've dated and the thousands of dollars spent, only 1 woman has returned the favor. How nice of her!
