Friends are liers?

[Jenn A]

There is this guy named Josh right? And my "best" friend named Miki, or so I thought. Me a Josh are best buddys but then one day he's all like I know who u like, in a flitish way -__- Then I get pissed off beacuse the only person I told was Miki. So I asked her about it and she said NO she NEVER told him. She thinks he found who beacuse I "gave it away". I didn't belive it but I let it go. OK so One day Miki calls me up and asks me to ask out Josh over MYSPACE for her so I agree, I log into HER myspace account and Pretend I am HER and ask Josh out. So I'm like cool, so I go into her account and start talking to him. I say "I saw that u posted on the bulitons that u think the girl u like doesn't know. It's been bothering me for a while PLZ tell I promise I'll keep it a secret." Then a few min later he replys "I know you will tell. You want to know how I know? Becuase u told me who Jenn likes" I was mad this isn't the first time she lyed is she a friend? She lied to me and idk what to do
