MOD MOD MOD!!
I haven't been hanging with my bff lately because I'm tired off her posse. I talked to her and asked her if she didn't mind that we all didn't eat lunch together(I asked her today at the end of the day). She seemed kind off embarrassed and like laughingly about it, it seemed like she did care but she denied it anyways. When we hung out a couple of weekends ago, she told me that I hang out with my friend lets call her K a lot. I feel like we do because we have tons in common and have all of our classes together. (me and my bestie have none)It's not intentionally but its not like she doesn't hang with her friends in her classes a lot. Another prob I have is that my bff is hanging with this girl that did lots of damage to us and our friends, I don't want her to get hurt maybe the girl changed but I doubt it, and I feel like she's taking my place because f im talking to my bff and she starts talking my friend gives the attention to her. HELP!

Maybe you should talk to your friend, but you also have to let her make her own decisions. If she's a bad friend, you warned her and she learned her lesson.
