Is it normal for a bff to do this? even though she claims she is "straight"

When it was my birthday my best friend and me went out to see a movie, and as soon as the lights went down she started getting close...she was so close I thought she was going to kiss me! And she did kiss me but she kissed me on the cheek but she kept coming close making me think she would kiss me on the lips! Do you guys think she wanted to actually kiss me? I AM ALSO A GIRL! Oh and we went out some other time to see a movie and she kept holding my hand and whenever I would let go she'd get upset! So do you guys think she might be interested in me? Like as more than a friend? She's touched my ass, boobs, and vagina before.
