Hey, i'm a tad stuck with what to do in this situation i'm in..........basically i met this really hot girl about 3 months ago, we're still in regular contact with each other, either via txting or speaking on the phone. I have been on a few dates with her and everything so far is going according to plan!!

( touch wood), my head!
Now i have recently got tickets to go see a top gig, i've invited her and she said that she'd love to go. She also said, 'just let me know how much i owe you'.........now i've not said anything yet. I think the best thing to do is obviously not charge her anything because at the end of the day, i asked her to come, seems a bit harsh to charge her aswell. What do you guys reckon!!
Thanks
