She's becoming very close but says she doesn't like me?

Anonymous

So I became friends with a girl about 6 months ago. She knew I developed feelings for her but she told me that she didn't feel the same way and thinks we're better as friends, and so I began seeing new girls and she began seeing different guys vut we kept hanging out as friends, going for a walk together once a week. Recently though, she's began to act differently. She says she still has no feelings, but I've noticed that everything I say now is hilarious to her. I've been told to check for body language and things like that but it's hot and cold, sometimes she has no issue with us touching in flirty areas, and others so doesn't like when I stand close. Sometimes her body is open towards me and others it's closed. In every aspect she gives off very hot and cold vibes. We've began to get very close though, especially recently. We go to the cinema together and we went to the beach the other day, where we ended up wrestling and she just giggled, before going for lunch and she wanted to share a dessert together. Last night she came by with a Chinese and came into Mt bedroom to watch a movie together. At the start she was very stiff and sat on my bed corner, then eventually she started wrestling me a bit on the bed and by the end she was laying beside me completely facing me. Yet, once the movie ended she got straight up and left. She had no interest in a chat, or another movie or anything just straight gone which was so strange. I've been told that she's probably now started questioning how she feels and the recent change in our relationship is her seeing if she'd enjoy being with me without risking our friendship if she doesn't, and that the best thing I can do is keep making her have fun and allow her to keep coming towards me, as if I make a move I risk scaring her off. However I'm not an expert so I'd like some advice? she's done a complete 180 in how she treats me. I was always a friend, but now she jumps between super hot and just a friend
