aquarius and there best friends

my best friend is a aquarius and lately me and her have been fight a lot considering im a leo i need attention and shes one of my only friends, so she has these 6 friends and lately she'lll always hang out with them and when i want to hang out she always comes out with a excuse why not to hang out, she tells me she rather me tell her my problems with her so i did and she completely got upset with me because i said she can take pictures with her other friends who shes know for a year but with me she wont, and that she'll always find a excuses why not to hang out with me and that its not right for her to let them call her there best friend and she flipped saying she doesnt understand why she cant hang out with other people and that i was calling her a horrible friend, and at this point i have no idea what to do cause she loves to give up and i just wanna know what to do.

I agree with both options presented above. Two questions:

Are you the type that can only have one friend at a time or only one best friend?
There are several people who have more than one best friend. I think she's trying to spend time with you, but she also has other friends she wants to spend time with too. The more pressure you put on her, the more she will distance herself because she doesn't want to be bombarded with all this. She may think you're acting jealous or needy and clingy, so to save the friendship, I'm thinking you should give her some space for other people. Also, maybe organize an outing or a sleepover and invite those people too and all of you hang out. If you get to know them, you might like them and vice versa. But, sometimes, friendships drift apart for one reason or another and it's usually no one's fault, you just develop different interests.

Is she hanging out with girls you don't like or who don't like you?
That one's trickier. It might be that you should try to make new friends. If she's gotten in with the wrong crowd for instance, you don't want to get involved with them. Or if she's hanging out with the snobby kids, well, that won't be any fun.
