Everyone need your help?

I really like this girl i work with and everyone I work with knows that I like her. I have know her for 2 years. I guess that today when they were all eating lunch someone said that I am like totally in love her and I guess that she just laughed and the subject just dropped. Well I went to hang out with her tonight at her house and we just kinda hung out and download a bunch so different types of songs. such as slow fast all different kinds of genres. Then I just kinda started messing around with her hair and she took it out of her pony tail. Then we were just listening to some of the songs we downloaded and there was this one song it was slow song. that song from love and basketball when they have for the first time. I kinda looked at her and she was like twirling her hair. I really want to make the moves on her but I dont want to ruin the great friendship we have. the question is do you think she likes me? Do you think from what I have told you should I have put the moves on her?
