Good friend or bad friend?

Ok so I have this one friend who i met a while ago. I'm going to call her sarah. So sarah and I have been best friends for a while now. We are both in middle school, in the smae grade and have many cles together. So we have been both doing different activities and we have een both making a bunch of new friends. Ok so we both do a sport. I'm going to say that it is tennis. So we were both doing tennis. She had started a few years earlier than I had, but she wanted me to join, so I did. She had made a few new friends in tennis,a dn they all seemed pretty nice so I was ok with it. But then she started putting stuff on youtube about her and her tennis friends doing stuff together like hanging otu and stuff and that was hte day I asked if she could come over and she always says she can't. So at first I was a little suspicious, then it got wiereder when she put on her page for something I love all my friends and then put a bunch of her friends naems and I didn't say my name on there. I wasn't worried. Then she was telling me abut ehr friends and she siad that she was sorry that we haven't hung out in such a long time, because when she has her tennis friends there is so much to do becuse they do the same sport. and I just thoguht that was a little wierd because i play tennis too
