If I were in your boots I'd stay dark too. Considering all the crazy emotional stuff in your H's life right now, I believe that taking a break from him will be healther and more healing for you.
There were times during the divorce when I didn't want to talk with my husband either. I told him to please limit any communication with me to email or text messages, and also to let me know in advance when he was going to pick up and drop off kids so I could be away and avoid seeing him.
This wasn't a game. I just didn't want to see my H. I felt like I was mentally happier and healther without the contact.
You are entitled to your space. Also, now that he's an Ex he has absolutely no claims on your life, no say in what you do who you talk with etc... My husband would say this to me during the divorce and I made sure he realized the same held for me (and believe me that seemed to bother him a lot more than it bothered me!).
There is no arriving, ever. It is all a continual becoming.
