[Jewelz]

I am best friends with this girl and i have never given her any reasons to doubt me...or to not confide in me but lately she seems withdrawled and she wont tell me important things!! It isnt that we dont spend even time together because we spend alot of time together!! but she seems to tell my other best bud everything....that just hurts!!It upsets me and i dont know if she even realizes that it does!!All i know is that i want her to confide in me and i dont know why she wont!!does any of you have any suggestions!! i could use them right now!! that~~~Jewelz~~~
