I've been doing pick up for a few months now, seeing lots of girls, but there's a girl I've been hooking up with that I'd like to turn into a girlfriend. I think she's really into me (she made the first move as I was initially resisting and recently after sex said she has "a good feeling about me". I'm not exactly sure though how to start hanging out more and transition into a relationship without putting myself out there a bit. I've put up a bit of resistance to us hanging out too much, because I want her to feel like she needs to win me over, but I want to be careful I'm not overdoing it and making her feel like I'm not as into her as she is into me.

Basically, I feel confident in picking up girls and getting sex, but am not sure how to turn something casual into something serious. Some of you might say just to let it proceed naturally, but I got into pick up after I realized my natural way of approaching girls wasn't working as well as I wanted, so some kind of strategy would be nice :)
