thats annoying. i hate people that say cheerleadings not a sport, cus you honestly wouldnt know unless you were a cheerleader. yeah maybe like sideline cheerleading isnt a sport, cus i can agree with that. but competitive cheerleading is DEFINETLY a sport. you probably couldnt do half the that a cheerleader does. get your facts straight....
talk to your friend about it first. i was in the position your friend is in now. at first i was pretty mad at her for liking my ex, but i realized i needed to accept the fact that i was over him & that i need to let him be happy, & my friend be happy. im sure your friend will do the same thing just as long as you talk everything out with her first & atleast get her permission. she might not be okay with it at first, but eventually shell accept it. trust me
