sarcasm does not pass through the TXT barrier, unless you know a girl really well, or you use more emphatic, exaggerated language and lots of emoticons. you deflated her right off the bat in that one, and it wasn't exactly clear that you were kidding. Either:
"Yeah. I guess so. Meeting you was okay. ;-). If you play your cards right then maybe we can do it again. ;-)"
"If you play your cards right, then maybe we can do it again, little hen. ;-)"
Would have been a LOT better. I'd still maybe drop the sarcasm of the first one. She obviously expressed "kind" (not playful) interest in you, and you cut her down. Maybe if you were real sassy on your date, you can pull it off. Oh, and don't make grammar mistakes.
