It could be that you are looking for something that doesn't actually exist, and you just think these girls are what you are interested in.
The trick is to get happy with your own life enough that you don't project a 'needy' vibe. Believe it or not, this will be attractive all by itself!
Also, there are huge numbers of females. The world is fifty percent female. I'll bet some of the females actually ARE interested in you and let you know. Think of them as a mirror-- you are sending out vibes that attract that kind of woman. To attract another kind, you change the signals you send out.
But also you have to send signals that are not faked, that are actually part of your natural abilities. Falseness will repel people, unless they are also fake.
