if she does not initiate any text message to you it might mean
that she is a conservative person and she thinks that it is
inappropriate for a girl to initiate contact with a guy.
OR
she is just not that interested to talk to you anyway and she
replies long messages to you because she sees you as a friend and
she is just being polite and courteous to reply to your text
messages.
she does not hate you because if she does, she will not even
bother replying back to you in long sentences.
if you are interested in her and wish to go after her, just call
her and ask her out for a specific date and time and her response
will tell you whether she is interested enough to give you a chance
to win her heart. don't waste your time texting her, she will not
fall in love with you because of your constant texting.
check out my articles at my blog, it will guide you on how to
properly go after her without turning her off.
