Should I leave her alone or keep trying?

me and this girl talked for a couple months about a year ago. we eventually went our separate ways due to the fact that we had different wants out of the relationship. After we stopped talking she eventually started dating a guy a couple months later...They just broke up about a month ago. I then saw her at a bar a week ago and we flirted the whole time and even kissed a couple times. She then went on to admit to me that she never got over me and that I was the one she always wanted to be with and wants to be with me. However, ever since that night we haven't really talked much. I've attempted to text her but the conversations quickly faded. I've attempted to hang out with her and she said she would let me know and just didn't ever contact me letting me know. I'm really confused. Is she acting this way because she just broke up with her boyfriend or is she playing hard to get? Or is she just not interested and was lying to me (which i find hard to believe cause the truth comes out when intoxicated). Should I give her space and see if she reaches out to me or keep trying?
