i'm a girl, why other girls don't like me?

Me too I have no girl friends but then I have no friends in general so...

Insecure people often see QUIET people (like you) as being a snob.  Even if you are not one at all.  They can only go by what YOU show, and the less warm and outgoing you are, the more the insecure people will think you are like this because you think you are superior to them.

You mention yourself that you hope you didn't seem cocky at the beginning, which makes me think that this is the problem.

I have a friend who has low self-esteem because of being bullied as a child. She becomes insecure when meeting new people and as a result overcompensates and then comes across as arrogant and full of herself, and sadly this has people not liking her. Once you get to know her and she starts to relax, however, she's a lovely person. 

If you think you might have a similar problem, I would urge you to try and analyze your behaviour when meeting new people and try to work on it. It can sometimes help to prepare in advance, act, and "fake it till you make it", especially if you're shy and uncomfortable.

Women can be very different. One thing that is common is they judge people. Possibly when you are quiet they assume you are judging them and then hate you for it; I have witnessed that crazy pattern. It is very easy to offend a woman by doing nothing. You must blabber to put them at ease. You must put yourself out there so they can approve of you before they invent who you are in their head. Create a list of small talk topics prior to your next encounter to be sure you interact. Inquire about anything interesting about them and let them talk. After that you can try to get to know them.
