It's fall. Good time for long walks on your own. And while you walk, you can tell "him" all those things -- about how mad you are at him for doing x, y, and z, and how you don't understand how he could.
Because you're probably gonna get answers as good from the wind as you are from him.
It sounds like a really good time to deliberately spend time apart and work on your respective recoveries. (((hugs)))
