i have this one friend group where we're all really close with each other but recently we all cut ties with this girl (person A) because she was being kinda mean to everyone beside this one person (person B) in our friend group. Anyway, i have a class with Person A and my friend, Person B. When we go into class Person B always leaves me to go and talk to Person A. Like they leave me to go sit with them because they're by themselves but then when they leave, i become by myself. (I sometimes move with them because i dont wanna be alone but Person A is always giving me looks). But after class Person B talks with me and the rest of our friend group like normal. Should I talk to Person B or just leave it?
