How to deal with INCONSIDERATE FRIENDS!?

Welp, What can i say? Shes kinda a jerk, Im gonna admit it, Shes my friends though, Well, for example, one time, we were playing American idol, and hwile she was singing( P.s this was over the phone) And i was paying absoulutley full and undivided attention t her. Well, here somes my turn, She starts by saying she dosnt really like Paramore, right before i started singing Brick by Boring Brick. Okay, tht didnt bug me too much. Then i was singing, She totally wasnt listening! I could tell ccuz i heard her yell somthing to her mom, she could at least tell me to hold on for a second, i wasnt even done with the song when she gave me my grade, AND she gave me A SEVEN! NO biggy, i know i did better. That part dosnt bug me. Okay, another time, i broke up with my bf on Facebooks tinychat( a video chat thing) and i was acting really sad and she said ," Whats wrong??" And i said," ME AND AARON JUST BROKE UP!!" And she acted like it was no big deal! I dont get dumped very often, so.... (He was looking all googly TOwards a girl doing a handstand in her hallway, agin this was video chat.) oh wow, i typed thi sis like 2 min. NEW RECORD!!!Anyway, i wanna still be her frined, but wanna change her, oh she also is a total downer
