She keeps touching me, could it be because she likes me?

We're both biual and I do have a feeling she likes me. She is always putting her arm around me when we walk together, whether there are others around or not, although lately it's been like a shyer touch and she pulls away a bit quicker than she used to. And in the movies, she keeps leaning into me so our arms are touching..Now, those movie seats are quite spacey, so she obviously has enough room on her side. I take it as she just wants to touch me. And once we held hands through an entire movie..actually held, not gradually let go so we were just touching, but actually holding on. Now granted, the movie was scary, but not every scene was scary..So how would you interpret that?
