If you decide to post a reply, just say "thanks" and leave it at that. In many situations, we have to be the better person and bite the bullet just a wee bit. When I'm not sure what to do, I ask myself, what would I do if someone that I work with, neighbor, family or friend had behaved this way and then later apologized. If you say that you would respond with a "thanks", then do so.
He knew he had crossed the line when you held your ground, so he had to back peddle and apologize. BTW, nice work on standing your ground.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
