I thought about messaging her about the book but I’d feel weird about that too

The girl never got back to me so I guess we’re not hanging out tomorrow?

I can’t message her again, sadly, I already double messaged. Even though I’m kind of worried because last time we didn’t have a real plan (well, we knew what but I told her to tell me what time would work) until I messaged like ???are we on for tomorrow or?? (and then that was when things got pushed back a day and she turned it so I had to pick a time) So the same thing could be going on now? Idk she seems so enthusiastic about hanging out but then?? I’m not sure what’s going on.
