Never tell a woman how you feel romanticaly about her. if she's smart she'll pic up the vive. always make ur mark (not words) that you care for her, but dont need her at the same time. Woman fall for what they cant have or tame. The minute you become to available, guess what?........... NEXT GUY!
Make sure you always have other options and let her see that indirectly. NEVER NEVER NEVER develope oneitis with any girl no matter how hot she is. (google oneitis)
Dont forget by the time she's 20 yrs old, a cute/hot babe's been aproached or hit on more than 1000 times. how many aproaches you think any guy that age have made so far? not even a fraction of that. So women will always be ahead of the game since early age, (Specially hot ones)
