Signs my crush likes me back? Am I overthinking?

So here are some signs my crush likes me back but I'm not sure if they're actually signs or not.

​

1.) She got me a Christmas present already, it's just a small (like 1 ft) mini-Christmas tree with some decorations. As far as I know she hasn't gotten anyone else anything yet.

2.) I made my crush a playlist of songs that make me think about her, and also of how I feel most of the time. I sent it to her and she thanked me then the next day told me she's been listening to it.

3.) Also I called her cute and adorable the other day and she seemed to like it a lot, others call her such things all the time but she seems to (could just be my imagination) to respond more vibrantly to it when I say it.

4.) We were talking about a situation that happened a while ago and it came up that one of my friends was mad at me because I'm still friends with her. The way she said it was, "is he mad because you're still (she paused as if thinking about it) friends with me?"

5.) When I asked her to a school dance thing that's in January she said, "I would but I'm already going with (insert other guy's name here)." The way she said it made it seem like she would have wanted to go with me more than the other guy but he had asked first .

​

That's it for now, I may be overthinking but idk. Help me decide if I should make a move next time I hang out with her.
