Here's my take on it going by what you've described thus far:
Yes, if he was wanting to actually get to know you and form a bond with you then he would keep in contact with you while you are away.
I would say that "quality time" to him is his way of saying that he want's to invite you to do something where sex as the next step will be easy to manage.
If I were you, until you know him better and he is showing you that he values you more then just a prospective sexual partner that you keep your meet ups to public places and that you do not go to his place or have him to yours too soon.
I think his eyes have lighted up to the fact that you'd make the perfect non-committed partner due to your only being available two weeks out of every month.
If you would like more of a relationship of the romantic kind and not just the sexual kind with him, then don't put yourself in the position for it to be only sexual. Simple! If he cares, he'll stick around and he'll court you as guys who have solid interest in you will do.
Good luck.
