I’m falling for my ex

Ahh okay I falling in love with my ex. Is that bad? I really really like her, and I’m liking her more everyday? Should I ask her to the dance? What should I do??

Here’s some background:

We are both 14 and we dated in 7th grade and now I like her again. She is bisexual, but she says she leans more towards guys. We are getting really really close and I think she may know I like her? I mean in a group once we were talking and she was like “Emily, no one has a crush on me rn right?” And I was like “pffftf yeah” and she said “I mean I would want to know if anyone liked me but I would feel bad if I didn’t like them turning them down”. Am I over reading things? I mean we talk almost everyday and next year we have almost all the same classes together so ahh.
