Why would my crush screenshot my Snapchat texts?

Anonymous
There was this girl who I had strong feelings for, and yes she knew I liked her. She had previously added me as a friend on Snapchat and frequently uses the app with a 600,000+ snap score, while I was just a new user. We attend the same school however we do not talk and aren't friends.

Anyway, during lockdown, she decided to hit me up and sent me a snap that said 'Hi X', we started snapping and chatting. I started off by saying nice things to her and then began flirting with her. As I did so she started screenshotting the chat. She said bye and then left.

I'm honestly not sure what happened, I asked one of her friends and she said maybe she likes it. However, she sort of started ghosting me after this and would often leave me on seen or delivered. Her friends all know about the screenshots indicating she's been sharing them.

The chat is below, was she into me or was she being friendly or polite?
These were the Snapchat messages, and about as far I ever got to be with my crush.

I can also remember the chat off by heart, and it went something like this.

Rose: (Snaps me and says Hi X)
Me: Accidently sends hot photos of my face into the chat, deletes them, and eventually snaps her back)
Rose: (Screenshots the chat)
Me: Hopefully I'll get to see you when my lockdown ends
Rose: Me to
Rose: (Screenshots the chat)
Me: ?
Rose: Sorry didn't mean to do taht
Me: Xo
Rose: How's life been Nathan
Me: Oh good... how about you?
Rose: doin great
Me: Haha nice to hear x
Rose: Nathan
Me: Yes
Rose: Nevermind
Me: kk
Rose: Bye nathan
Me: Good night
Rose: (Screenshots the chat)
Me: ?

Anyway, after this occurred I was talking to a friend about her a few days later and he told me she didn't like me, did I do something wrong because I'm now terribly confused over what happened that night.
