Rejected the arm around her?

I went over to girls house whom I previously met safely from internet in front of the gym. I brought over a movie then low and behold that was the type she was telling me she didn't like! So I told her to take it out and we can played some xbox. Then I put in one of her sappy movies that she hadn't finished watching. Tried just easing my way over and putting my arm around her she told me that was to much?

So I jumped up and sat on other side of couch and started texting other girls. Watched movie for little bit and ran out the door and said bye lol..

She texted me and said she liked me yadayada I'm old fashioned. I've never gotten a reaction like that I didn't know what to do.
