Confused to as to what should I do next

Dear friends I am in love. I'm fairly sure of it. What I am not sure of is whether or not I hurt someone by being that way. I can't even tell whether my cognitive bias makes it as though she does like me but actually doesn't or vice versa. It's a very stressful and lonely thing, and makes me paranoid that others will stop communicating with me because of the lonely mood I am in right now. I am otherwise a rather relaxed and fairly confident person (at least ever since I went on a break from the internet for a while, which made me let go of being involved in petty stories that would otherwise not have any relevance in my life had it not been for the web), but yesterday a lot of things changed.

First off, I went to a party. I attend them somewhat regularly and usually find myself enjoying them, but the moment I left the house, even in my best clothes, I already felt uncomfortable (maybe it was because I was going to a club I'd never gone to before), and this discomfort only got worse when I saw that my, I guess, "crush", came along with the group of friends I was in on the way. All of us were hanging out in a park by the club, drinking, smoking, etc. It was objectively a pretty good time. But I still felt anxious around her. I'd already interacted with her in the past, helping her out sometimes on projects, engaging in small talk during breaks, etc. The most I'd done was give her an adult colouring book (as I noticed she finds them relaxing), just because. She'd told me much later (after apparently trying to get to me for some time) that she liked it, and tried to bring the conversation even further, regarding work stuff and so on.

Anyway, as we went in the club, loud music playing, etc. there was a fair amount of youngsters coming to dance, eventually. Why wouldn't I join them? We jumped along and stuff with our hands on our shoulders, while she and her friend (who is rather extroverted and comforts her sometimes, since she is rather shy like me as well) danced together. I invited her with a gesture to join us by pulling her towards us a bit, and she gestured back as if to say "I'd rather not, thanks". Maybe she simply didn't want to dance, but then again she also didn't seem to feel uncomfortable with physical contact with other people. So, I have a bad feeling I'm the problem. But I'm really not sure. Did I make her feel obligated to return a favour of some sort when I gave her the colouring book? Did I manipulate her? What did I do wrong? In fact, her not liking me is a secondary issue compared to the possibility that I made her uncomfortable. Or am I overthinking it? I've been told I am my own worst enemy quite a few times in my life. Should I go further?

I just don't want to hurt her.

Another thing I noticed is that my emotional intelligence dropped to half of what it was. I'm serious! I did a test in one of my better moods the other day and got a relatively high score, and the one I took today (the same test) was really rather low.

I think you may be over thinking this. You invited her she declined....nobody’s boundaries got crossed.
