Hi I'm new to being a being a PUA so I'm definately more of an AFC.
Anyways, the other night I went to the movies with a friend and two girls. We all drive in my friend's car to the theater. (Yes I know, movie dates aren't very good) Girl is showing alot of IOI. I keep smooth talking, negging and using kino. Here is where the first problem comes up. The girl I am trying to get with is very picky when we go to choose a movie. Everyone else wants to see one movie but she says she doesn't like it. We talk her into it with her being a little upset. We all sit down in theatre after getting drinks and the movie starts. About an hour into the movie I put my arm around her and she moves in closer. Soon we are resting on each other as the movie goes on. I wait until a good moment then whisper something and go in for kiss-close. My friend who is not knowledgable about PUA is sitting there not doing anything. Anyways we make out for about a minute then stop and we continue sitting with my arm around her. She seems more quiet now and I get worried it could be my performance while making-out. I go in for another kiss later in the film and we start kissing again, harder now but then stop after a couple minutes once the movie ends. I am sad that it ended not sure if I am a bad kisser or something or maybe my breath smells. She seems much more quiet. I am now speculating that it was something that I did that made her now not turned on.
We walk back out in a group but she and the other girl (friends of each other) walk ahead of us guys and talk, whispering.
In the car, we sit close and talk, at times I feel her moving in as I speak, but then again she doesn't seem as enthusiastic as earlier in the night.
I revert to AFC ways when I ask her whats wrong and say, "Are you sure you had a fun night, because I know you didn't want to see the movie?"
We get back to our cars back in town and we go our separate ways. I don't kiss her goodnight because everyone else is right there, again an AFC. Aghhhh. I simply say,"Bye, talk to you later!" Then go home trying to analyze what happened.
She definately wanted to make out at first, but what was it that made her seemingly lose interest? Was it me acting like a wuss by feeling bad that she didn't get her movie choice, or maybe poor skills in kissing?
How should I go on with this girl? PLEASE REPLY.

Thanks,

I'm not sure, this is a new one on me.. I would have taken steps to freezing her out.. First ask "Is something wrong?" if she says no as she did here take your arm off her and just sit there watching the movie.. She'll feel weird and ask you if somethings wrong, you tell her that she's too closed off and she shouldn't be afraid to open up to you.. Now you ask her if something wrong again and she should tell you.. Once you've identified the problem you can take steps to deal with it..

I hoped this helped
