If you want to attract women but they won't even give you the time of day, you are definitely doing something wrong. Most likely to one mistake you are doing is to show that you are interested in them. Now, before you assume that this is too absurd, read on.
There is actually a way to still show interest in a girl and make them attracted to you. But first let us take a look why you are getting rejected just because you let a girl that you are interested in her.
The reason why you usually get rejected by girls as soon as you display some kind of interest in them is because you show it too much! The thing about showing too much is that by doing that, you basically tell her that you are needy and just too desperate to meet her. That you want her attention, badly. And no woman wants to get into a relationship with a needy guy.
This is way your best strategy should actually be to show less interest in her. To keep her guessing whether you like her or not. This way, she might even take it as a challenge and try to win your attention. But how are you supposed to demonstrate disinterest, when you can't show interest? Well, this is quite simple.
Instead of being in her face and telling her how much you like her, start a conversation normally with her and show a little interest. But as soon as you see that she might find it a bit uncomfortable, take a step back and play it cool. This way she is never going to be sure about whether you like her or not.
Now, there is actually a great book that goes very deep into this topic. It is called Models: Attract Women Through Honesty (http://www.alphamalementality.com/models-attract-women-through-honesty-review). It will tell you how you can show interest in a girl without seeming as too needy or desperate.
But if you are just starting out, showing her that you can hold some distance and actually aren't that interested in her, will work wonders. But you have to find a balance, otherwise you will just go from one extreme to the other and this will work against you.
With this little trick, you can make women attracted to you. It is just something you should start with and you shouldn't rely on it for long. If you do it correctly though, you can attract the women you approach.
