I (18m) met this girl in a dating app, we have been talking throughout the week and stuff has gotten a little hot over chat. Yesterday, we set a date for Monday, kept talking for a couple hours but let the conversation finish with a message from me. I have not texted today (it's already 11 pm) and was wondering if I should text at all before Monday. I'm planning on texting her on Monday before the date to confirm but I don't know what to do tomorrow, or even today later at night as we have talked till 3 am.

I don't want to be too much, and at the same time don't want to text first again, she usually follow the conversation extensively but don't think she has ever texted me out of the blue as I have.

I would like some advice here, I kinda new to the dating world. (Also give me some tips to verify if she's actually her, never met a online girl irl).
