I met this girl one month back and went on 9 or 10 dates. I was having great time with her and I think she was too. Last Sunday we watched a movie at her house and she asked me to stay, so I did. Also, we decided not to have sex until we know each other very well. So obviously nothing happened on that night. But, since Sunday, she hasn't called me or replied my emails/txt messages/phone calls. She is kind of reserved person and I have been having hard time to read her mind. But, I guess that attracts me more towards her. She also introduced me to most of her friends and she was considering me as a potential boy friend. But, something has suddenly changed. Where exactly it went wrong?
