So far, so good.

I'm sure it'll get weird again eventually. :)
Oh, I'm sure it will. A lot of what I've observed here on SI, and in the lives of those around me, is that these things come in waves. I think of it like the ripples in a pond when you drop in a stone - the waves are bigger and closer together at first, but over time they become smaller and further apart, until eventually they go away. The ex's temper tantrums are often the same way - big and frequent at first, but over time, as long as you hold consistent and firm with NC, they get smaller and the time between them lengthens. Breaking NC is like dropping another stone in and creating new waves.
This was on it went for a few years until she met her current BF who actually was single and a decent dude. His influence on her allowed us to verbally communicate without drama. So far things are going well and when I pick up or drop off our son I can actually speak to her without any issues. Found out a couple of weeks ago that she broke up with the BF. I'm kind of hoping they get back together as she leaves me alone when with him. But I'm also preparing for her to begin her shit all over again. First uncivil conversation and its back to verbal NC. Its a great system in there is no room for the X to lie and/or make accusations. The written word can not be disputed or challenged. Just make sure you don't allow her to entice you into the insane banter they so crave. Keep it short and sweet, on topic and no more from your side. If she has the need to vent of attack you let her. Its all written down to use as evidence if needed. Make sure you save all of the communication should you need it at some point. Good luck to you bro, this is a great tool to use for healing and peace of mind.
How do I avoid verbal contact if I have to exchange DD? (most of the time there's no words exchanged, but sometimes there are)
Think through anything you have to tell her about dd ahead of time and you can quickly burn through the list - behavior, health, school, obligations that weekend, whatever. Think of it like a business meeting where you have an agenda and you stick to it without wasting time.
What I like about the NC thing is that it goes in both directions. I care much less about her life because I know much less about it. More emotional distance over time.
