I met a girl a few weeks ago at this music concert...at first I was reluctant, but by the time she had glanced over at me for the 3rd or 4th time(smiling the last time) I initiated conversation with her, and we hit it off almost immediately. By the end of the show, we were walking around the street, arm in arm while she waited for her stepmom to pick her up, and we exchanged skype sns a little bit before she left, all with my voice just about gone as a result of getting over a cold.(this worked out when I asked her what was the best way to get a hold of her when my voice wasn't completely shot...we got sidetracked a few times and I even changed the subject to see how she committed she was to giving me this info, and she did indeed go out of her way to get me her info).
I wanted to try to get her number but she mentioned not having a working phone of her own, and mainly communicating by borrowing a family friend's cell or using the house phone(I initially thought this might be bs, but after hanging out with her again a week later, where we made out, and then having sex with her the following week, I feel like it wouldn't make sense for her to intentionally keep her number from me for that long)
Current Situation: She's been sick recently so we've only been able to talk on skype lately..ever since meeting her I try to only talk to her every other day or every 2 days to give her enough space to miss me. We have good conversation, and she still seems to show signs of interest. Even though she doesn't express herself as much on skype, whenever we see each other(once a week usually) she tells me how much she misses me and that she would think about me alot. Even though things seem good so far, I want to be able to keep this girl interested, and keep things from fizzling out..hopefully even take thing to another level at some point since I'm actually starting to really like this girl.
Even though I've had some success with women in the past I'm still very new at thinking of things from a PUA's perspective and have the most trouble keeping girls once I've managed to get with them. What should I do now?
