How would you go about that:

So, i picked up a hot and very attractive med student (another one).

This one is very feminine and submissive, calm and introverted. She was studying for a coming exam at a coffee shop i usually go to.

We had a long conversation, sparked some tingles in her and we exchanged numbers.

We've been texting sporadically these last 2 days and she wants to setup some private time (date? Is that even a thing nowadays).

The thing though is that she's busy with her exams this week and on the day of her last exam, friday she'll be traveling for a bit within the country.

So it'll be a while before we get to meet one to one.

My question is how to keep the attraction.

I just lost a girl because the attraction fizzled out due to me being out of town a lot over the last few weeks (the replies where taking longer and longer to come each time) and I don't want a repeat of that.

I also don't want to be in her face all the time.

What's the right middle ground?

For context, she seems inexperienced (muslim and all), not the party type, quiet and studious and due to being that reserved and attractive I can tell few men actually approach her.
