So I met a girl at my Crossfit gym a few month back. I've interacted and flirted with her. I've made statements like "of all my cuter GFs your the worst" and we still have communicated. My intentions are apparent. We have been texting and snapchating at times. Tonight I asked her out via text.
Me: "hey would you be up for (blah blah) next Thursday or Maybe going to see (blah blah) concert Friday?
Her: "oh Brad Paisley! I'll have to see how I feel after Bruno Mars

"
Me: "well I have 2 tickets"
I was thrown off because that show is on Wednesday and I was asking about a Friday show. Like I'm going to wait until next Thursday to see if she's "up to it"
Seeing I've replied already I don't know what to do. I can't really say anything witty or that would retract my invite but I also would like a yes or no so I wouldn't be in a position to eat the ticket. I feel like I could say would uninvited her and allow another guest but I'd rather take her.
What would you do?
