Ask how she is. See if she replies

Don't send anything else until closer to the time. Don't want to look too clingy

Just say
'did you get home yet? Because I need to plan it a few days before we actually meet. If you're busy, then that's fine'

so i was talking to this girl yesterday and she flirted with me complementing me and everything, bare in mind i did not complement her. she asked to meet up with me on Friday and i agreed. today i realized that i cant to meet up with her because i have a class.
