Get advice from someone who's probably been in the same boat before.

From Emily:

“okay so i have this really good friend named Gemma, and we've been bsfs since we were little kids. lately she's kind of started ditching me to hang out with the cool kids. the other day i asked her to go to the mall with me and she said she was busy so i asked my other friend emersyn to go with me instead and while i was with emersyn i saw gemma hanging out with her new friends at the mall. what really crossed the line though was when we went to this girl's birthday and we played spin the bottle and she had to kiss the guy i've been talking to. she kissed him for a little too long and i think she's doing it to make me mad”

My advice:

I think honestly you should look at your friendship with Gemma. If she’s always been a nice, kind person and you don’t typically have issues in your friendship, then maybe you should see if there’s something else going on in her life that could cause her to be mad at you or suddenly want to stop being friends. If you can sit down and talk about that and work it out it might be helpful to your friendship. If you’ve had a lot of problems before, you might want to think about letting her go. It can be hard to say goodbye to friendships you’ve had for so long, but it’s much healthier to let go of people who have been a constant problem in your life. If you think she might not be the best person to continue being friends with, then maybe you should focus more attention on other friends and people you care about like Emersyn, I promise it will have a positive impact on your life.
