You stole my best friend now I'm left in the dust...

Ever since you came to my school and met my best friend I knew this was coming but I didn't expect it to be like this. You came and you took her like that. I know you have a bond because your parents are both divorced and you came from around the same area in Texas, but did you have to steal my best friend? I want to talk to you both about it but all you'll say is " I can be friends with who ever I want""Your not the boss of who I'm friends with"" Why do you care you have a different best friend." And I do have a different best friend cause my other one was stolen from me. And you always treat me like shit and get mad at me for no reason. You tell me lies and think its funny when you tell me the truth and say you were just kidding. When you make fun of how me and my sister fight and I get mad but you think its funny. You don't see anything wrong with the way you treat me, and here I am sitting her crying because i finally got this off my chest and I don't know what to do. Because you stole my best friend and now I'm left out in the dust...
