Would you be angry if your "bestfriend" did this?

[Big Nasty]

Well basically we haven't talked since last saturday so it's been a while. She broke her phone but she hasn't called me from home, or on Facebook or anything, albeit I haven't talked to her either. Plus she's been going with this guy who actually is my cousin (I'm a dude) and his friends. Now I don't mind that she can do whatever she likes it's her llife. I just feel like she should of sent me SOMETHING. I mean if you're my "best friend" I should come close to first. I feel like you should want to talk to me, seeing as I'm not just your friend from school or some nobody . If she didn't claim me as her best friend I wouldn't care, but since we are, then act like it. Plus on twitter she did one of those "initials of someone you care about" things, and she did three people from school who she said didn't come before me. I mean what the hell? Am I nobody all of a sudden? Should I be upset about this? I would like your thoughts. We're really close like brother and sister, but lately she hasn't even acknowledged me. Thank you.
