I think the problem
lies in your mindset. Previously, all is easily won. But now, the
game of pursue is no longer simple. It seemed that getting the
woman you want requires more than just plain chatting on the phone
or dinner at classic places.
Ladies do grow up too you know.
And as they grow wiser, they are more resistant to 'tricks'
employed by guys that might easily score well with less experienced
ladies. Also, they are often so overly exposed to interesting tales
of BGR stories from their girl friends that they learned some
things from here and there. The more experienced ones are even
worst; they anticipated your thoughts even before you date them
out.
You craved for instant gratification... instant affection...
instant answer... like instant noodles; allow me to encourage you
to see the beauty of patience. There are things in life which you
got to work for and these things are often worth the effort. And
working towards this goal requires time and patience. Like brewing
a pot of chicken soup, if you shorten the time to brew it, it
probably doesn't taste as good as if you allowed all the time
needed to make it an excellent pot of soup. 
Cheers
