First of all, English is not my natural language so I hope there will be no misunderstanding.
I´ve been trying to develop my skills for 6 months now. I set my goal to get two dates per week, trying to open sets in every posibble enviroment(bars, clubs, streets, swimming pool etc.) in order to make mistakes fast, so I can learn fast...but now I´ve met a girl and yes there are feeling involved and I don´t wanna screw it up(which will most likely make me screw up eventually

), so I decided to join this forum and ask for help or at least your opinion.
Let me summarize:
1) I´ve met this girl about a month ago at disco, she noticed me before in her hometown(altought I did not), so she asked me whether I live in that town and I said yes. We talked about 20 minutes, I got her number and then I said I have to go meet some friends and moved to another sets.
2)Next day I noticed, she added me as a friend on facebook. I accepted and wrote her a message: ,,What are we doing tonight?" and I got a meeting with her at a quiet local pub, we had few beers talked a little about hockey. That´s it.
3)Then for two weeks she was busy so we didn´t see each other. I was fine with that cause at that moment no feelings were involved. I moved on and almost forgot her.
4)After two weeks I met her at local music club(Jimi Hendrix revival)...I noticed her and decided to take action, so I walked pass her, gently pinched her ass and smiled over my shoulder while passing her. Went straight to the bar, order wiskey for me and her favourite drink, laidback and waited whether she´ll come join me. Althought many times before this worked(women are curious), she did not come. But next day she texted me ,,What are we doing tonight?

" I invited myself over to her place with bottle of champagne to watch movies. She agreed.
5)We really had fun, mood was set, kino ecsalation went really well like never before, but she got sick from the champagne and threw up.
6)Next day I called her in order to ask whether she´s fine and I invited her to come to my place. She came, I continued kino escalation, we kissed. No sex.
7)In three days I happend to have some bussiness to do in city where her university is and asked her to show me the way around when I´m done with it. She agreed and we spent whole day together, idont know 16 hours maybe. (usually after four hours with girl my head is about to burst)
8)So now she is attracted to me, fingered her,she wants to be seeing me...trouble is there is another guy, whom she likes and who refused her, so she is confused and doesnt know what(or whom) she really wants and because of that she doesnt wanna fuck me. I told her that I WANT her but I dont NEED her.
What is next strategy? I was thinking to not see her for week or two so she has time to miss me...
