Began texting a now married ex from years ago. Casual at first and then flirting more. 2 steps forward, 1 step back. She was completely unreceptive to flirting at first, responding with things like "gross".

She texted me first the following day and up until about midnight. More flirting which she didn't return but seemed more curious about but also said she would never ever want to see me again.

Third day, I text first and say: "stop making me dream crazy things about you, gah!" She asked about the dream. I make up this very sensual dream and put "...it was a total nightmare" at the end. She invites me to workout with her. I say no and she says "I guess you won't get to see me in my tights then." We're now supposed to secretly get together tomorrow. How would you guys handle this interaction with the end goal being same day sex?
