Betrayed by my best friend?

Me and my best friend have been besties since 1st grade and we are just about to enter our freshman year of highschool. It was always just sort of the two of us, no third or fourth person. We rolled as a two person group. When we were in 7th grade we kind of befriended a girl named Alisha that sorta followed us around but we weren't too close with her. I personally didn't like ehr at all cause she was so fake to me, but she really did like my best friend Les. So the nest year Les and Alisha were getting closer, but me and Les were still besties. Then all of Alisha's friends started to hang with Les and our two man group soon became a huge possy. I hated everyone of Alisha's friends cause they always invited Les over and I was always odd man out. Then one of the girls started this lie that I called Les a ***** and she believed it. We avoided each otehr for about 3 weeks until one day she just randomly strarted to talk to me again. Hold on I'll write the rest in the details!!
