I met a girl online, how do I find if she is interesting to know me?

I met this girl online and we've been talking through text, we share the same interests so is kinda easy to talk, but she is kinda hard to get, the other day I flirt a little and she said "I could blushed right now but I have to lock in" what that even mean? And she finds ways to talk to me even after she is very dry, she asks about my day and how I'm doing and she just throws random things about what she is doing or what will do, is she interested o know me or not really?
