Dear Emma dkcksjdjxn,
In bygone days it was considered improper for the woman to take the lead in a relationship...and I will tell you that in the Sixties a few of my guy friends told me how hard that was for them, always responsible for the initiative.
And now in 2016, it's okay for a woman to take gentle and gracious initiative.

I suggest you just keep up as you are, as long as things seem to be going well. If he is just being polite, you will know soon enough and you can back off then.
