Ok so that's the deal. I k-closed this HB about 3 weeks ago. We had a really good time, we saw each other after that night (with other friends), we had a kind of "connection" but nothing serious. We do A LOT of kino, always touching hands ect. Anyway about 1 week ago, I started to get bored about her so I didn't txt her or talked to her on FB. Sometimes she sends some txt/FB message but I only answered half of them. Yesterday, she txt me something like : "Now you are ignoring me..".
I didn't answer because I saw her this same day. I didn't even talk about that txt, we talked about what are we doing that night. We went out. We were about 15 friends including me and her.
Here's the deal. I went to dance with her, and she started a kind of drama about me ignoring her...I was like ok there is the attention you want, let's go dance. She tells me "Fuck you" and went to the bar to get a drink with another guy...Btw, while we were talking, I said hi about to 4 friends passing by, including 1 ex. When I said hi to my ex and gave her a hug, she was pointing at her and acting like I did something wrong.
I was like ok, she's always rude but I didn't get that part where she didn't want to dance. I went to the dancefloor anyway. I started to dance with a random chick. The HB saw me and she started to dance with guys that we came with. I clearly saw that she wanted my attention. Anyway I didn't talk to her after that. That same night, we saw each other on a restaurent after the bar. I was with some friends while they were eating all together. I went to there table to say hi and they started to talk about one of the HB I met that night. I was like nice, they are DHV me.

I didn't say anything to her (only hi when I said hi to everyone).
When they were leaving, she came to see WITH one of the guy she danced with. They were holding hands. I told her "I don't want drama, I just to have fun girl." She didn't answer to that. She only asked me if I want a sip of her drink. I said No, then she told me once again that I Fucked up.
Someone please explain to me what happened? Did I really fucked up things with her? This already happened once. We didn't talk to each other for about a week, then when we saw each other on a café it was a lot of fun.
