Going to a movie with a girl I really like, help!?

if i were you, i would jus go with the big group of people, you two can still kind of isolate yourselves from the group by sitting next to each other, and talking to each other n stuff like that. try wrestling the arm rest with her, if u see her hand on it...push it off n be like "this belongs to me" or something. n she'll be like nooooo n find a way to flirt back, then after that you guys can share it or something. slowly throughout the movie try to hold her hand. it'll happen, but just go with the flow. maybe try resting ur head on her shoulder for a quick second, so maybe later on during the movie she'll put hers on yours. ya dig?
