It means you're a nice guy, and all that that entails. She's already figured you out. Deep down, women want their men to have some mystery to them; to keep them guessing. A lot of guys think showering a girl with compliments is the way to go, but it's not. That just shows the girl she can have you if she wants. She needs to think she has to work to get you. Just as a cat loses interest in a string if it's dropped in front of them, a woman will tend to lose interest in a guy who says "Here I am." Dance a bit just out of her reach. You'll get her interest, and she'll want to see if she can get you.
That's what I've read in "The Game" anyway. I haven't nailed that down myself, but I have plenty of experience to know showering them with compliments only lands you squarely in the "nice guy" category.
It's hard, but keep trying. The people who succeed the most in life are the ones who've also tried the most and failed the most. Most self-made millionaires have had a dozen jobs before they found the right thing for them. Someone once said "If you want to have more success in life, you need to double your failure rate."
