I went to a party a few night ago and I notice this girl checking me out. She comes over to where I was standing and starts making it really obvious she wants me to cover over. I tried to act like I didn't see her and she stayed there for like 10 minutes until I did. We danced for a little bit and I can't dance so it was awkward as fuck. I introduce myself then leave for a little bit and she does the same thin with coming over 2 more times and we dance again.

Each time we would start grinding but her friend would be right next to her so...? The whole time I was there and we weren't dancing we are exchanging glances. Towards the end people started to leave and when I ask her if she's staying she goes, "nope, I'm with her now."

I guess my question is how do I escalate this/see if she wants to do anything else?

Side note: Are you supposed to be hard while dancing with girls? For the most part I was but a few times I wasn't.
