I she socially anxious or attracted in me?

Hi
I'm looking for advice
There is a girl, classmate. We don't talk and we aren't friends. We had few occasions to say few words when we had group work in school.
And I Remember at first time I spoke to her she blushed.
From some time, specially when I started Nofap, I started noticing that she may be attracted to me
But I would like to be sure because I don't want to fall into some kind of paranoia
I will list things which I observed, sorry if it will around cringy
That is what I noticed:
Today we were having a two hour length presentation and I with my classmates had to seat on chairs and listen to them. And it turned that she was sitting next to my right.

Usually when we seat near each other she seems to feel nervous.
Today it was the same of course.
She fix her hands, legs ect
Sometimes I touch her by mistake, and sometimes it happens that we touch each other.
I saw that she fix her hairs, she touch her mouth, Face, and I saw she sometimes looked in my side.
One time her hairs touched me.
Once I touched her hand by mistake and she turned her head down when I did it.
Sometimes when she was changing her position on chair her knees moved in my direction and then stopped and she was sitting like she was kinda avoiding touching me.
I saw how she avoids to touch me when she was moving her left hand from her hair to put it on her leg. It was subtle but noticable
Once I was Looking at the presentation and I saw how she quickly glanced at my face. It was like one second to the left (my face) and then to the neutral position.
Of course she also often did something using her left hand so it was noticeable by me.
And once we had to stand up and it was like, I was standing kinda behind her and she like quickly touched me by her back. I know this because I wasn't moving in her direction so she did it by mistake or not.
One time I changed my position on a chair and she did too.
At some point I started feeling some cool smell from her like a perfume.
That was nice by the way.
And there was a time when we all went to classroom to take our backpacks and go to other classroom and it was very tight at the leaving. When I was leaving she wanted to come in and we eventually touched each other when I was passing her to go out from the classroom.
I'm not sure if it's okay to post that here but I want to hear someone's advice.
I will probably spend more time in her absence now because I will have one class each week with her and one guy. And it turned out in a way that I sit with her.
And yes, she acts nervously at class too. And smile when I said something funny to my friend.
Am I just overthinking?
What do you think about it?
What to do about it?

 

"I say you start a conversation and ask her if she wants to hangout sometime."
Uhh, this is part is interesting because I feel nervous around her too. And the socialising is challenging for me because I have anxiety when socialising.
I'm really not an expert here. I don't even know how to start that with her. I mean, I don't even know what to say to make this sound normal not awkward. Because when I'm nervous I have blank head and don't feel natural, I always analyse my thoughts and what I do. Even when I write I check and analyse what I write and make sure it doesn't sound cringy.
Any advice? :/
