What are the signs girl changed her mind and does not want to go on a date?

I asked a girl out and she said yes. Her two bestfriends were telling for some time that she likes me and pushing me to do something about it. For some time we could not find a day when both of us are free. Now we met at the party and we barely talked cuz she was all the time somewhere with her friend. It seemed weird to me cuz when we met at something like this we always spent a lot of time together and her bestfriends who always were pushing now told me that she does not know what she wants and they wouldn't be surprised if i give up on her. They said that they think i am right for her but it depends if she knows it too. I haven't talked to her about it yet. I mean i shouldn't like listen to someone else but it seems weird cuz they always wanted me to be with her and they were really happy when i asked her out
