I met an amazing girl last night. She's so amazing, I want to get to know her better. This is a girl I want to have as my girlfriend. However, I don't know her quite well yet. We won't meet up for at least another week (too busy to meet up next week).

My question is, when do I ask her about her intentions? Is it too early to ask her now, should I wait until I meet her next? Or is it OK to ask now, after only meeting her yesterday? Maybe she's a girl that kisses new guys each week, and has no intention to start a relationship. I do not want to put effort into something that has no chance of succeeding from the start.

UPDATE: Thanks for the replies so far! Very helpful. I've talked to her, and it's clear to me now that she wants to see me again. She seemed genuinely interested, so I guess that's cool.

About the one-itis thing, I'm actually looking for a solid relationship, but haven't met the right girl yet, and this one seems to be it (so far so good, at least). Perhaps this was the wrong place to ask this question (I apologize), but your replies were very helpful either way. Thank you. :)
