So I approached this girl who I've never spoken to before and I fucked up. How do I un-fuck? How should my next interaction with her be like?

I thought I'll do some small talk but I had like no time and this is kinda how our convo went.

Me: Excuse me.

(She turns)

Me: Hi what's your name?

Shakes hand

S: Hey I'm S.

Me:Nice to meet you S. My name's A.

Both just smile

Me: So I'm gonna be honest with you yeah? I think you're really cute and I'd like to get to know you better.

S: Is this a truth or dare?

Me: No way I'm being genuine!

She giggles

S: Uh I don't really like ...uh relationships.(still giggling)

Me: I just want to get to know you. What's the worst that could happen? We'll end up being good friends.

S: Giggling intensifies

Me: So I'll tell you what , lemme get your number and we'll just talk.

S: But I don't have a number

Me: Wow you're 16 and don't have a phone? (This was kinda dumb and douchey I agree)

S: I'm seriousssssss.

Me: Okay well , atleast tell me if it's a yes or a no.

S: keeps giggling

(I was running late)

Me: You know what? Just think about it.

S: Alright sure , I will.

Me: Alright see ya later.

(End)

My heart was beating out of my chest and my eyebrows were twitching omg. I feel like I've screwed up bad , but I was happy nonetheless because I mustered the courage to approach her. What would be the best way to right this clusterfuck?
