We're both mid-twenties professionals. Me (dude) 23, her 25. Both Americans in the northeast. So I met (OkC) a seemingly wonderful woman who seems to really be into me (dude) and likewise. I asked her out, but she's on a business trip for 2 weeks or so, so she set a date more toward the middle of the month. I've been playing nonchalant and she's been eating it up. She gave me her number and has called and messaged me. I know she digs me (from her being proactive and our conversations). How do I prevent the spark from fizzling out before we get to meet up in a couple of weeks? I don't want it to go stale. Meanwhile, I'm still taking out other women, but I feel like this one has potential.
