Girl keeps getting very close to me?

She keeps making physical contact with me, like, she'll get very close with me on the sofa and her arm will always be brushing up against mine. Even if I move the other way a little she will soon be rubbing against me again.
Why does she keep doing this?

We are good mates which makes me think she doesn't. We share a lot of personal stuff.
