There's a girl in my study group, 8/9. We had a good vibe going, and I gave her a ride to her house because it was raining. I didn't number close, though I got a few IOIs. I figured I'd go for an instant-date after the next study session next week, so it'd be more natural.

But, she didn't show up and now I regret not going for the number. The thing is, I have her email through the study group (She didn't give it to me).

Should I send her an email, or just chill and hope she shows up next week?
