Your Opinions on this girl

Sup MW forum,
New here, got into cold approach a little over a year ago. Was posting on another forum, discovered MW, so now I'm here.

To my story. Met a girl a few months ago. 1st time was brief, I transitioned to her friend, ended up being annoyed by her, and left set. 2nd time saw in same club, re-approached she remembered me, went into insti-date, after several escalation attempts she told me that she liked me but yada yada yada. I left set because it felt like a waist of time.

Last weekend around 3am I see on the street, she yells my name and runs up to me and gives me a hug, and tells me she was looking for me all night. She was in a mixed set on her way home, got her number, texted a few times durning the week.

Last night around 9pm she text me asking if I'm going out. We meet up later that night. She's with a friend I hadn't seen yet. Chillin' with the 2 girls, another guy shows up who was meeting up with the friend. Now we're on double date. I'm taking slow remembering how it went the last time, but still escalating. Leading her around either holding hand or her holding my arm, constant contact, hand on back, rubbing arm, picking her up, being very physical in general. But every time I go for the kiss, she would give me the cheek and tells me slow down.

Fast forward to 3:30am, we all just finish eating, I try to move the party back to my place but she says she wants to go to bed....alone. She gives me a hug, and when I go to kiss her again...Cheek!

Anyways, to the point. I'm sort of stuck as to what to do next. It's seems like to me this girl wants me to be her boyfriend before I can fuck her, and I don't want that. The obvious advice would be to just move on. And that's most likely what I'm going to do. But at the same time, this chick is fuckin' Bad, and I don't want to just be a quitter.  What if I'm like one or two small dates away from hittin it and I just give up now.
Plus I'm thinking she one of those girls that actually hasn't been with a lot of guys based on her back story (in her late 20s, recently divorced from her high school sweet heart)

So yeah, what'd ya think?
