Do you think I was to nice to her?

There was this friend (i dont feel like useing real names but im going to call her "Lily") I had in 6th grade and she started off ok i would truly always follow her around and do what she does im pretty sure. we were "best friends" at least thats what she thought but i didnt agree because i had alot better friends but of course i didnt say anything cause i didnt want to be mean and stuff and she was my only friend in my class. later in the the year she and her friend she had a fight with became friends again (ill call her sarah) So then lily kept ditching me for sarah but i didnt say anything and also i wasnt the only person to notice she was COMPLETLY ditching me for sarah. so after awhile she apoligised because everyone was getting mad and i accepted it. and the of course later in the year lily ditched me for sarah again but i didnt say anything again in fact i would try to talk to her and same something nice but she would just like roll her eyes and answer with "attitude". and we became friends again but i would always notice her flirting withi my...boyfriend (yes i know im only in 6th grade and i have a boyfriend i know its weird but its just a long story and please dont talk about it in your answer) and i didnt say anything. So to sum it all up she was a jerk to me all year and was only nice to me when i was her only friend there for her and theres so many other things she has done. So after 6th grade (this summer) we were friends and we hung out sometimes but i actually hated her because of all the things that have happened in 6th grade but i didnt say anything because i didnt want to hurt her feelings. But then she texted me and told me to me call this number that when you called you listened to this recording that pretty much told you the person that made you call this doesnt wanna be your friend anymore. and it could have been a joke cause it was sorta funny in a way so i asked her and she never answered me i sent her like 5 texts and tried to chat her on facebook. Was i to nice to her? any advice? I just dont even know what to think.
