I think you 2 should meet and you should kiss her. Do that tomorrow or saturday.
Her initiating conversations won't last forever, her interest in you won't last forever. Set a meet up and kiss her.

Btw, if you don't answer it's ok. It means you have something else to do than talking with her. If the next day she calls you out on that, it means she's interested in you (another ioi). You answer something like "oh I was doing x and I forgot." What's wrong with this? Nothing mate.
