Please advice major relationship dilemma

I asked the girl i like a few weeks back to which she said "As of now No but i dont know about future if something happens". Thus we did not talk to 3 - 4 days and suddenly out of the blue she messages me saying "Baby, I havent seen your face since ages." We were supposed to go for a concert, which she was inclined that the two of us go for together but we ended up going separately. She asked me a lot to meet her somehow and she also told me that she is cautious because she thought i was distant and aloof. We met eventually where she gave me a lot of attention and it felt like she wanted to be with/around me. I asked her if she would come for a beer with me, she said yes. I met my other friends whom I asked to join they agreed. Suddenly out of the blues she said "No, I will go home and catch up on some sleep." Now again suddenly she is cold and distant. I don't know what she wants. She is very warm when we meet in person but not when on texts. Also, initially when we didnt talk for a few days she showed the initiative to meet but not anymore Does she like me, still? and does she want to have more out of this friendship now?
