i choose my friends

i choose my friends, like the people who i want to be closed with. back in 9th and 10th grade, we had a group (6 ppl including me). theres this girl (lets call her nise), nise is kind. us 6 actually lasted for a year. in 10th gr, nise decided to hangout with other ppl in the class. we did not told her "go to other groups" and blabla. she decided to hangout with other ppl bc theres this time in math class where she wanted some answers from me and anne and we told her we will teach her how to get the answer and somehow she got mad??? like we did not know what was wrong with teaching her how to get the right answer. and theres a task by group and we tried to invite her and she declined, and bruh after that task, she got mad at us bc why she wasnt in our group. like bruh that was bruh moment for us 5. so we decided that we wont bother her, like if she wanna join the talk (or in our group) then ok we will welcome her. but she decided to hangout with other ppl and that was the end of us 6. but us 5 are still together. tho nise and anne are still in contact, nise's presence is kind of exhausting for us 5 bc of shes energetic and the way she talks. she wants it that its all abt her, just her own topic and no one shall make a new topic. i dont want to call her toxic, i just decided to talk abt her bc her actions (math) were kinda toxic at that time. but we hope she will finally be in a group where she can be herself.

this shit kinda confusing but i did my best (not good in english)
