boy does this shit sound familiar.
the more PUA you do, the more chance you'll run into this situation (not because of how often you PUA but because you're thumbing thru more women). it's rare though, but every once in a while, you'll get a LJBF from a genuinely "hurt" girl - recently broken up, still looking. it has happened to me twice since I started gaming 5 years ago.
you have to seriously take control of the situation and maintain it, it depends on alot of factors whether or not she'll make it easy for you.
depending on how it went before, i would not acknowledge her via text message at all (it's okay if you already have, but don't start chit chatting her in text - this gives her the validation and attention she is asking for without any "commitment.")
If I were you, I'd call her in a few days (mid-week, mon/tues maybe?) and do a phone call only, no asking to date. but propose something fun you're doing without inviting her ("Oh man, I'm so excited this week to hit up this brand new restaurant in _______. it's gonna be killer") make sure you change topics after that quickly so that she doesn't get caught up in it (she will be wondering who you're going with and why you didnt invite her, etc.) make the phone call short, 5-10 mins max. the time will fly by. Also, dont let her VENT to you about her life. if she starts venting, cut her off and be like listen i just wanted to see how you were i can't really be your psychologist in the middle of the day/evening today/tonight
- use cocky/funny tone)then call her a few days after that, ask her to do something casual and make sure it involves heading back to your place at some point. have her meet at your place then run out for coffee or a bite to eat. easy as hell. game as usual when you get back to your house "oh come in for a minute i want to show you something since the last time" then have something fun lined up at home (video game.. music.. movie, whatever) and f-close it up
