I don't know how much you need to know about the situation, anyways, she had birthday, i first went to her house with a couple of her friends, then we went to a club, and basically everyone left us there to go somewhere else where we'd go later. So it was us 2, we had fun, talking, dancing, building attraction. We did Kiss but i pulled back really quick, because i originally wanted to close outside because inside you dont really understand what the other is saying except for if you scream in his ear. So after that i go to the dancefloor for only a few minutes when a guy sits next to her and they suddenly start making out and im like wtf. Just kept on dancing and eventually left with my friends without seeing her again. I did send her a sms asking if she is still coming into town with me to meet with her friends or if she went with random guy. Didnt response to that.
So to the question:
The next day i sent her a song she wanted to know yesterday and i got this back:
ah thanks
), i was just writing a sorry - sms because of yesterday; 
i am really sorry for 1. leaving you alone 2. because i have the feeling that you are not so happy about me always leaving with xy,or is this no problem?My question now is, is this a shit test given by her or is this her way of saying that she is not sexually interested. (we're pretty good friends, i do a lot of c&f and kino though, but then again i am 16 and she is 18 )
Just wanted some opinions because some people said its a shit test and others meant i should give her up
