So, there's this girl that I called "pretty" on instagram and she liked it. A day later, she sent me a friend request on Facebook and accepted her. I started a conversation with her, we talked a lot and then told her if she wanted to go for a drink. She accepted and she told me she'd let me know for the day (she's on holidays from the 1st August).

So since then (Sunday night), I haven't talked to her and I'm just waiting for her answer. Imho, I don't want to talk to her cluelessly, she said that she'd let me know so I'm waiting and I'm giving her a bit of space. Plus, if we cannot see and are not going for a drink then I have no intention in pursuing a conversation.

Should I wait for her to let me know about the day and if she doesn't, then good loss or am I supposed to send her something at some point?

Edit: She liked one of my profile pictures yesterday (even though I didn't update it), which was pretty random tbh.
