How to get a girl to like you enough to say yes.?

[Roy]

For valentines I gave the girl that i had a crush on a teddy bear and flower when i gave it to her she was very happy and seemed trilled. We both are very shy so i didn't ask her out at that moment but I later asked her trough text. She didn't reply till an hour later telling me that she prefer to be friends and that she just wasn't looking to be in a relationship. Later that day I found out that she isn't really aloud to date from one of her friends. I also saw that she posted a pic on instagram of her and the bear at a sleep over she was at. I need help this is really hurting me and I know that the girl is really shy and doesn't like to date but i need anything I can get.
