Firstly ,damn... 2 months later ? i think thats a pretty long punishment u gave her for not complying the first time lol.
when she replied saying " would u like to take me to this haunted place ?", u shoulda went cocky + funny ( said soemthing like : Iono im quite tha busy man, but i guess i can pen u in my schduel ! lol ) and then schdueled a date ( u already gave her a 2 month punishment no need to play harder to get ,she gets it . )
When u did reply with " tonight seems perfect" u must of forgotten that tonight is TONIGHT, not everyone isn't doing anything lol its why dates are schdueled in the first place to guarantee availability. Her saying " Maby next time ", is a girls way of letting u know that the world doesnt just stop when u want it in a playful way.
Other then that if u want to sew up things with her and recover from that AFC answer , i would call her INSTEAD of txting. and act as if i never said /texted that sort of reply and if she refers to it again act as tho u completely forgot about it , turn it into a joke ( C + F ).
Pretty much let her know your still cool and u were jus screwin around/ didnt think she would take it so serious
she lock her sense of humor ina box ? GL !
