Hey guys, what's up? I'm tryinng to figure out something really weird that happened yesterday, maybe someone here could help me out.

I've met this HB8 last friday, she's a friend of my friend. Anyway, we've met in a bar, and after some talking she was showing lots of IOIs to me. She left with my friend and gave me her number. On monday, we hanged out with our friends to drink and grab something to eat and there she has shown more IOIs. I could've ended the night with a KC, but I had to go to the subway, because it was closing.
Finally on tuesday, we went out to a cafe and a bar, where we kissed. After that, we went to a hotel and had great sex and slept. On the next morning, she was really clingy and happy. I left her home and we kept talking.
Yesterday, we were going to watch a movie with a few friends, and she was looking forward to it. Then, her friend (not the one that I know) told her that she (the friend) wasn't going anymore, trying to hook us up. The left the HB8 really mad, and when we met, she was avoiding kino and conversation. During the movie, she slept (she was a little sleepy), and when she was awake, she kept looking to her watch.
Since she was being such a bitch about it, I didn't give her much attention, and I'll probably talk to her only on monday. Well, I have two questions:

1 - What the fuck has turned her off?
2 - Should I wait to talk to her, or was it a bad decision? Should I say something in specific?

Thanks guys!

I think she's playing games here man! Its either she's on a major period thing or she's testing you -- you should of said "boy your not as fun and adventurous as I taught you were" or "what happened in the movie ... I fell asleep" something !!! You seen her check her watch that means she wants to leave but can't because she doesn't wanna hurt your feelings and such, so she still likes you in some degree but you HAD to kino, kino is key !! -- mehn why couldn't you be compassionate for five seconds and just see what was on her mind --- I still think she likes you tho ,

Hmmmmm yeah, I know that kino is REALLY important, but she didn't let me touch her, I don't know why, maybe she was embarrassed because we were not alone and stuff, who knows... Then I guess I should contact her right away, right?
