Does this girl like me?

So some background, I knew this girl for a little because of people I know knowing her but recently we got to talking a lot more and she says she's one of her closest friends, even sharing things she hasn't shared to anyone else (thats what she says anyway). She got out of a relationship a while ago and I've liked her for a little while now for a week or two. But the reason why I'm here is because I'm stumped on whether she's into me or not. We were hanging out with friends and we're sitting right next to each other and she puts her head on my shoulders, then after a few seconds took them off and acted like it never happened. Help me so I don't completely make more of a fool of myself than I already have
