Awww, 1carazy675, I think we have all been there sweetie; it's all part of growing up. I was going to marry Liam Gallagher when I was 15. In hindsight, it's probably a good thing that he met and married Patsy Kensit (or Fatsy Hensh1t as I would refer to her as) at the time, and I moved on..... *sigh*
It doesn't feel like it now, but it probably is just a crush. You will get over it, and you'll forget who she is... until someone like you reminds you in years to come (like you did with me LOL)!
