Going NC is just for the both of you to cool down and really think through things. Think about it, both of you not contacting each other, and the both of you can let matters go just like that? I think not.
Since he hasn't been in any relationship before, there's a chance he might not know what to do, which is why he didn't contact you. Some guys have the mentality "since we already broke up, i don't have any rights to speak to her. If she wants to talk to me, she'll contact me"
Being with him before, you should have a rough gauge whether would he feel this way. This may be also he has low-self esteem and don't really know what to do with girls.
If you really care for him and want to lubricate this whole issue, take the 1st step and contact him. If you don't want to contact him 1st cause of some "pride" issue or "guy must contact 1st", then think it this way.
Does all these matters, when you can get back with the guy whom you love and really want to get back with him?
This is just my opinion. I hope no offence is taken
