Long story short, about a month ago I went to a dance club with a female friend who actually went out of her way to be my wingman without me saying anything. We began talking to these two girls who were there, and we went inside to dance. One of them was a real troll, but her friend was gorgeous. The hotter friend, Amy, and I did a bunch of dancing, and from time to time she'd go up to my wingwoman and ask if she was my gf, or if I was single. Basically the wingwoman told me that Amy was crazy about me. At the club they played that song "Call Me Maybe", and at the end of the night I said to her "Hey I just met you, and this is crazy, but let me get your number, I'll call you maybe". She immediately grabbed my phone and put her number in.
That was Friday - On Sunday I texted her to see if she wanted to get drinks and go to another dance party. She said she and her roommate (The troll that was with her on Friday) were having family over, but she said she might be free the next weekend. The Thursday after I sent her a text, and she never responded. She just went cold.
My question is this - The wingwoman and I were talking today, and I mentioned I was at the bar that I met Amy at. She asks me whatever happened to this girl, who was making it clear she was super into me. I told her what happened, but I was wondering if there's any chance this could be rekindled. So my question is, should I pursue her still? What should I text to get her interest piqued?
