Wow, for men this IS a problem. Please, next time do yourself a favor and analyze the situation just a bit more, you may think it's a competition and you have to act fast but if a woman is into you she'll stick to you like gum! Just be realistic and honest, if she hasn't spoken to you much, tried to contact you, get your phone number,you know, real ACTIONS (not just words or "signs") then she's NOT worth your time. We've all been there but loving someone that doesn't love you back is embarrassing and a complete waste of time!
