What should I do now about this girl?

I am confused of girl I like. Her friends kept telling me she likes me for a long time. We kissed and I asked her out and she said yes. But now when we were on a same party she was a bit distant and her friends told me that maybe i should give up on her, she is complicated, they are confused of her and that they think she doesn’t know what she wants. So i asked her if she really wants to go out and she said yes. I dont know what to think about this
