Someone close to her could have just died. She could be in the hospital. She could have been incredibly stressed about something terrible happening or about to happen. And you expect the first thing on her mind to be going out with you?
Umm... she HAD an emergency. You should probably believe it.
Cause she had an emergency she had that in her mind first. Give it some time and then text her "hey i hope everything is okay I'm here if you wanna talk" something like that. And then have al little convo with her and ask her if she would like to go out again.
