Okay, I am going to try to explain something... I work about 45-50 hours a week, I also intern, I work out daily, do belly dancing, soccer and volleyball... and you know what, I make the time to talk to someone I am interested in for hours a day, every day. People can never be too busy if they are really interested. If you like someone, you make time in your life. That "busy schedule" stuff is bullshit. Women use that as a nice way to say that they are really not that interested, without being an asshole. Basically that is the "When I have nothing else better to do, I will call" excuse, it is fucking evil and horrible, but the truth. My input would be to hang out as friends every once in a while and keep looking. If she really likes you, she will come around. If not, you have made a friend. And no sweetie, nice guys do not always come in last, you just have to find a woman that actually appriciates you.
