My bff is ugh

So my best friend and i feels like we are spreading apart. She's on a lower academic track, and just doesn't understand me on a level of maturity and emotionally plus my more advanced sense of humor and stuff, so I want to kinda stop hanging out. She always talks about not staring drama with guys, but she's already like changed her mind and made a big deal about 4 different guys in 3 weeks. Also, whenever I want to talk about how great my day was, or how I kinda like one of our guy friends, she always interrupts me to tell the whole world how shitty her day was. I just feel so annoyed by her recently and just ugh she doesn't understand me, and I can't even relate to her anymore. Ahahgajagdh
