How do i deal with this girl?

(Sorry this is long) Your friend isn't a very good one. If you feel sorry for her sometimes then just tell her to be friends again but not best friends. You should play with your real friends more often because you can be yourself. Your real friends have a right to not like your "best friend" because if i was your friend then i wouldn't like her. Tell her that she did mean all those things that she said to you during those arguments and if that happened again then you won't ever be her friend again. If you were her 'best friend" then how come she never believed you and believed your ex-friend? She doesn't know that a best friend is better than a friend and that two best friends should be at the same level. she getting mad at you for random reasons is stupid and thinking you are flirting with boys when you are talking to them is also stupid. She talks to boys and help them by doing good deeds for them, it seems as though SHE'S flirting with them. She doesn't know what she's talking about and I believe that being best friends with her is a bad idea. She shouldn't be asking you to do things for her and you shouldn't be scared of her. If you are brave and people believe in you (i do!) then you should stand up to her like what you did in the very last argument you had. Good job!! Hope I helped
