Girl's Behavior

Does she like me or is it normal for a girl to behave like this when she’s not usually touchy with our other close friends?

if I like a girl and she acts in weird ways, what am I supposed to do? For example, she always leans on my shoulder and is really touchy (she isn’t with others). Back in October we went to the cinema and she rested her head on my shoulder as well. Another time, we were at a party and i was walking by behind her and she grabs my hand and puts it around her waist while still holding it. The other day we were at a party and it was kinda cold so, out of the 5 people that we were talking to, she put her hand around MY arm to warm up and then put her hand in MY coat’s pocket. The same day she asked for my coat (which is weird bc there were tons of people that didn’t have their jackets/coats on so she could have asked any of our friends) and, as I wanted her to take a hint, I put it on for her and even closed it (also unbuttoned it for her when she had to leave). And also, we spent 10 minutes just sitting with her that had her head on my shoulder. These past days in school she does this at least once a day and today she kind of hugged me (she did say that she was eavesdropping a conversation but she didn’t need to hug me to do that since it was in the same exact spot) A couple of months ago she laid on me (sort of) during class. The other day we were walking together and she slowly put her hand around my arm when we were walking and she keeps on saying that she’ll come visit me to bother me in the city I’ll go to in 9 months. We were talking about a movie with another friend and i think i asked her if she wanted to come with us and she said yes under the condition that i go with her to see another movie as it comes out. I think I made it quite obvious that I like her at this point, but I can’t figure out if she does this just because she’s comfortable with me or if it’s because she likes me back. I also don’t know how to make her notice without telling her right off the bat since our friend that knows about this thought that she was the one that like me and not viceversa

Does she like me or is it normal for a girl to behave like this when she’s not usually touchy with our other close friends?
