Told a girl I like her, she said she doesn’t believe in relationships. Should I move on?

So guys I know this is kinda funny situation I've gotten myself into. But I sincerely don't know what to make of it.

So there was this girl in my marketing class which i kinda liked, she was intelligent, good looking and fun to talk to. So I've started liking her.

And I thought she liked me too, she used to smile at me often, she even gave me a death stares like girls used to do when they want you to approach them, and I caught her looking at me multiple times in class she also asked about me to my friends. Like my name and how they know me and some other stuff.

Since I've liked her and we had only one class together there was not enough time to build a lot familiarity,

So I thought why shouldn't I just confess to her and since she likes me as well things will be a lot smoother. So here's what I did:

Hey, X could we talk

So there's this thing I wanted to tell you for a few weeks, and I know this might across random and sudden but I have started to like you, I don't know but there's something about you which is really attractive to me.

Don't feel pressured to answer me right away you could take as much time as you need.

She smiled through my whole confession and said, what answer can I give you, I don't know. And again gave me a big smile.

I said the class is going to start so I'm going to leave you alone. Thanks a lot for listening to me.

She stared at me and smiled again and again in class.

After the class I approached her again and I apologized for being too straight forward and said I didn't even know that you're single or not.

She replied I'm like hundred percent single but I don't believe in relationships. Thanks a lot for liking me, but I just don't believe in things like this and again fucking smiled at me again and gave me a up and down stare.

I don't know what the hell I did wrong here.

Girls help a brother out, I really do like the girl. Should I chase her or should I start to move on. I'm confused 😕
