I'll post all details I have to make it easier to answer.
2 weeks ago, we went out to a club. We were 4 guys. Usually we split up in "teams" of 2 to pick up chicks. So me and my friend went to open a 2set of HB8 in the dancefloor. Total fail, both of them told us that they have a boyfriend. I answered "Cool you can invite him if you want" but nothing worked. Anyway I wasn't in the mood to work for a girl so I went straight up to another 2 set. This time, hb6-7. Not as hot as the two first. We started making out with them. Then our two others friends went to open the same 2set that told us that they have a boyfriend. They got "rejected" too but they still danced with them. Then one of the girl asked one of our friend what the hell are we doing with the grenades we had. I don't know what happened after that. In our case, we f-closed the hb6 we were making out with.
Our 2 hb8 went back to my friend's place to jump in the pool with them. Nothing happened between them though.
The week after that, my friend invited the 2 hb8 in a party with us. In fact, they didn't have a boyfriend (duh...). In the party, I was able to k-close and #close one of the girl that told me she had a boyfriend (YES!). We were close to f-close, at one point we were alone and she was on top of me in underwears but she told me that she had a bad experience before and she's not a slut. I said that it's ok but we can still have fun. So we continued to try hump and make out. I told her that I want to see her again and she said with a big smile "Me too".
I saw the same chick 4 times now, every single time, we ended up kissing. The thing is every time I was the one who had to work to get it. Like one night we were in a club, she was dancing and I told her "You're not that good dancing alone". She said something I didn't really heard. Then I said "Come dance with me". She said "No". Then I told her as a joke that she broke my heart and she's mean.

Anyway, I just put my hands arround her hips and we started to dance, then make out of course.
But like I said, I'm always the one who have to work for it at first. But only at first. After that she's often arround me and she initiate the kissing. I wasn't able to f-close her...I had 3 hard chance to do it, but she always find an excuse.
I may know why. I think it's because she saw me kissing another girl just before we met and she may think that I'm a player, so her bitch shield is really strong. Also, I have a lot of female friends that I know in clubs so I'm always saying hi to another girl but I don't think she's jealouse. Also last night we were kissing (we were alone), and at one point, she stopped and said "It's all you'll get" with a smile. I was life fuck, but I answered like a boss "I don't care, I'm fine like that". That same night, I texted her "Good night sexy, I want to see again".
I already invited her to a real date but she was working that day (It's true though because she invited me to come to her bar, yup she's a barmaid). I didn't invite her since. Should I try again or wait for her to invite me? She's the kind of girl that you actually have to date to f-close, damnit.
So I'm thinking to actually date this chick, she's hot and fun to hang out with. But how to break the idea of me playing her and how to proceed to have date with her? You have to know that I froze her for a few days because I was always the one texting her first. It worked because she started to text me after 2-3 days. Also last night I was doing a lot of push and pull and it seemed to work. But like I said, at first it was hard as fuck to even dance with her, even if I already k-closed her 3 times before that night.
