She thought I liked her... what should I have said?

Anonymous
OK I was texting this girl I'm interested in (but I'm not in love or anything yet), and suddenly she mentioned that she had not been texting guys recently as she wanted to concentrate on studies (exams were coming up next week)

the conversation went somewhat like this:

her: you don't have to keep texting me you know, I don't chat with guys recently so that I can concentrate (on studies)

me: I didn't know I was so distracting. okay cya in sch.

me: wait, I didn't do anything wrong right?

her: nope, no worries. don't think so much luh, we are friends.

me: lol what's with that last sentence? did you think that would change or something?

her: is that like a confession?

me: WHAT?! like, no? what's going through your mind, seriously.

her: haha. good! just scaring you. okay see ya at school.

me: haha okay. can't believe you actually thought I liked you -.- rofl.

...

and... I think I screwed up there. what should I have done? what should I do from here on?...
