Cold approached this dime of a girl 2 weeks ago. Went out the following day and hooked up. Last week we tried to get together but couldn't get our schedules right. She texts me out of the blue yesterday seeing if I was free. Just so happened I was. Made plans to meet up today. She texted me again today wondering if we're still on. I responded yes. About 3-4 hrs later she responds with a "sorry but I'm staying in tonight instead" text. Any thoughts?
