Okay, so I made out with this girl at a party last friday. She and I kinda works the same place, but she's in another department. We were both drunk and the kissing got very handsy and kinda dirty. It was cool.
The next day (saturday) I added her on facebook, and she was fairly chatty, talking about herself and asking me about stuff also. I then asked her: "When are you gonna give me your number" and she said something along the lines of "Maybe I'm gonna give it to you

"
So the morning after (sunday) I initiated the conversation again, and she was very chatty yet again. I then gave her:
Me: I know how I can get your number! You can give it to me when we'll hang sometime next week
Her: haha, I'll think about it
Alright, so yesterday (monday) I just cut the chase:
Me: So do you wanna get together this week? I can pretend that I can cook, and you can pretend that you like it.
Her: This week is pretty crowded, but can I get back to you tomorrow?
Me: You do what ya gotta do.
So today (tuesday) was the day that she said she'd get back to me, and I haven't heard from her all day (I'm about to go to bed). What do I do next? Should I just totally ignore her, or should I reinitiate the conversation, even though she said that she would?
