So a girl I know is interested (she's literally told me) and we've talked a little bit and hung out multiple times. First time we made out intensely (albeit both drunk) second time was much more composed and still made out and had a great night. We work together (probably not the best idea I know) and have talked a bit. Kind of stopped talking for a bit but we saw each other at a bar a few days ago and she was not only all over me but she kissed me. I asked her to hang out again a couple days later and she said she had plans that day and followed up with a "Do you work tomorrow night?" To which I replied "I'm actually off tomorrow". That proceeded to get no reply. Is she playing hard to get or should I drop interest?
