Affiliate Marketing Secrets

ok so there are two different situations i’d like input on.
1) Over the summer i became like bestfriends with this one girl. She’s not really popular (neither am i). Then, a few weeks ago we got in this fight over something stupid that happened in science. I apologized to her on facebook and then she said “lets talk monday” and we never did because i was really busy lol. then she gave me a LETTER. (not a note it was like double spaced, dated, and had my full name! serious right?) saying that she was willing to talk it out if i wanted to. i honestly felt like i had done all i could by apologizing, its not like i’m gonna beg to be her friend again! but now its really akward and i miss having her to talk to. but she’s still a *****. so idk what to do. advice?
2) Another friend has been acting weird lately. She hangs out in the library with a ton of nerd. and i’m not trying to be a snob but i’ve always wanted to be popular! especially in highschool. and i know thats not gonna happen by hiding out in the library and being anti social. and also my friend has been acting really weird like creepy and awkward. she says weird things and is kinda nasty sometimes. idk what to do. any advice?
Thanks and leave a link i’ll answer yours!
