<human>: Can you succinctly summarize the text in 1-3 sentences?

Ive been hanging out with this girl for the past couple of months (never alone, always with mutual friends) and it seems like she is into me, but whenever I make a move, I get put down. 

For example, this past weekend we went to a Halloween party together. At the end of the night she drove me and a couple of other people to her house so that I our cab could be cheaper. As I was leaving I gave her a hug and said "We should do lunch sometime." She said something like, "sure" and like squeezed my bicep. So the next day I follow up on that lunch offer. This is the transcript...

Me: Come eat lunch with me on Monday.

Her: When?

Me: 12-1

.......... (2 hours later)

Her: I dont have class until 2:30 tho

Me: Lame

........... (8 hours later)

Her: How is that lame??

Me: I got class at 1. You coming or no?

Her: Lol what?

Me: Idk

I have no idea what that means. Is she playing hard to get? Or is she not interested. 

FYI: One of her good friends (who happens to be my good friend) told me that he doesnt think she is into me but hasn't talked about it with her.
<bot>: Can't tell if a girl is interested. Almost all of my friends tell me she is. I think she is but whenever I ask her to hang out, I get non replies or cryptic responses. Thinking about giving up.
