Mmmmm awkward moments?

She isn't really talking to me anymore.. I mean as friends.. we used to talk a lot with good conversations now shes kinda like snobbing me, whenever I say sup she says sup, but I ask her how shes doing she just says 'good' usually she says good what about you etc with all these exciting things/emotions... this happened after she found out I had a crush on her friend... but I only see her as friends nothing further.. now she doesnt even talk to me at all... Whats up with that? I ask her whats she doing she just says chatting.. then the conversation goes quiet... we usually talk alot but not anymore..
