Because he told you that he needed space, he's the one who asked for it so I say if he wants space and he likes you, he will contact you it's just a matter of time. Wait for him to contact you and you said that you supported him that means that you've done something that he'll remember and you left a mark on him.

NC could work for you in a different way. The NC works very well to get over the person instead of hoping for them to contact you. Use the NC and assume that he will not contact you, that way you can forget about him and move on. Seems to me he will just come to you when he doesn't have anything better to do and will most likely end up using you.
