idk friends??

IDK if it's serious but i feel distant towards my friend and i don't want to be seen as jealous because she's talking to a guy but i sorta knew her before he did and i don't but that don't matter. at school when it was break time i was hanging with my other friends while she was talking to him. i didn't stood by her or talk to her because i don't talk to the guy really and now she walks with him, i get it if she needs a break from me but she could at least tell me..right?

TODAYY outside before going to my class i was hanging with her but she looked mad when i came over...I was silent but i don't wanna be silent all day because she gonna ask if i'm ok and i hate getting confronted. Should i talk to her or just leave it alone??

IF MY GRAMMAR IS BAD I'M SORRY
