why do my friends leave me out?

[Daydreonah]

I'd probably start looking for some new friends.
I'be been in a similar situation.
My best friend or just friend , Briana , has her Cousin , Roxi , to come over. When we were all sitting in the living room Roxi had got a call from her B.F. and Roxi had went in the backroom to answer the call and Briana follows behind her and so did I. When we had got into the room , Briana had asked me why I'd follow them back there. And a few minutes later we were back in te living room and Roxi was going to McDonald's and she had asked Briana did she want anything and left when Briana had told her what she wanted. When Roxi had left the room she told me that Roxi acts different and she thinks that Roxi has a crush on her B.F. and in my mind I'm like , how do you think I feel? Briana talks behind her back but acts like her best friend when she's around. And Briana always talk about how fake people are pathetic and stuff. And I like , really? You' re take yourself. But so far she' s been a ok friend. I just don't put anything past her.
