I would give this guy time, and some needed space.
He's got a lot going on, and maybe he needs the time to himself to figure out exactly what it is he wants from this relationship. If it's been on/off for that long, chances are you both (or one party in particular) will one day get tired of it, and move on to find someone else more compatible and a relationship more stable.
You did a good thing and apologized, and reached out to him. However, wait a few days until he contacts you. Let HIM do the reaching out to you. He will when he's ready to talk, and see how things go from there.
Let him calm down, and give him some time to get over everything that happened. Perhaps you hurt him more than you may think. I hope he gets back to you soon.
