I miss my girlfreind! and im 12 :(?

I am 12 years old and i really loved this girl. She loved me for an ammount of time aswel. Well first off i asked her out and we never really talked...i guess she was to shy to talk to me but i'd try to make attempts to talk to her. But just to clarifiy to her that i loved her i sent her a message telling her how important she was to me. I broke up with her soon after that because we never talked but then a few weeks later i felt like **** and i still do. A few months after this i sent her another love message but it turns out her mom read it ((One of her freinds told me)) And her mom was like ENOUGH OF THIS NONSENSE IT HAS TO STOP but she couldnt resist...but i wonder if she still likes me because she uses Decoys to cover up who she really likes and she says she likes this chinease kid. Whenever i look at her she stares back into my eyes for 2 secounds but she is really shy and always avoids me and i really love her ...how do i know if she likes me? She always is shy around me and always avoids me. =(
