first off, falling for a woman is MUCH different than a woman who is falling for you. you need to learn the difference.
if you find yourself texting her every 2 minutes and constantly calling her, you are just setting yourself up to be crucified. you will be crucified and it will be very painful. in all honesty, guys are pretty innocent compared to girls. for the most part we are pretty straight forward and say what's on our mind. we'll call our buddies to go play soccer on the beach for the sake of having a good time. girls on the other hand ALWAYS have agendas and they all play games.
lets say you've fallen for a girl, you don't really reveal personal things between you with others that ask you about it. you keep it private. but her? she has talked to ALL her girlfriends about you and possibly other guys and or ex boyfriends.
you need to start playing games with them like they are to us. when she comes back to your place and starts taking her clothes off, you have to tell her, "i don't think you're ready for me. i want to make a mental connection with you before we take that step in our relationship."
you hold out for a few weeks. she then realizes you are the one and starts talking to all her girlfriends that you're different than 99% of guys out there. because 99% of guys would have slept with her. this flips the power dynamic and she goes crazy over you.
also, women actually have a higher sex drive than men.
