Hooked up with a girl, and not sure how to turn it into something more

So I met this girl, we went out that weekend and hooked up. She texted me the next day saying she had fun and wants to do it again. She also made it a point to tell me she doesnt normally do that sort of thing. So it turns out that I have developed some feelings for her, and I'm a little nervous and not sure what to do next.

If she says she doesn't normally do that AND she wants to see you again, I'd take that as an indication of interest.

Ask her what she's looking for: something casual, or something that can turn into more. If she wants you to answer first, say you like being around her and you wouldn't mind seeing where things go. That leaves it open in a positive way.

If she just wants steady, casual hang outs/hook ups, you're feelings could be hurt and it would be good to avoid that.

Everybody that does "that sort of thing" will always tell you they don't "normally do that do that sort of thing." They say that because they understand most people think it's a foolish thing to do, not that it's necessarily the way they normally are.

Continue if you want but do it with the understanding that people (both you and her) that shoot first and ask questions later stand a much greater risk of missing the target than those who take a steady and more considerate aim.
