Tonight, I went out to a bar with friends. I was having a good time with friends and this girl showed up, who I TAed last semester. We talked and had a good vibe. I asked her if she is single, she answered positively and we exchanged numbers. Later the night I ran into her again, and we chattedmore. And she kept leaning into me to speak, and I remembered a post that I should make kisses playful and I kissed on her cheek. And BAM she just went cold. Maybe I should have done more kino. Before my friends and I left, I asked her "are you still up for hanging out?" But she gave me some negative vibe. But I still got her number and I have a chance to meet her again. She said she will be gone for the weekend. At this point what can I do to make a come back?
