Update.
A couple of hours later my son called. "What's up?" I asked.
Just called to say, "I'm sorry."
"Just that."
"OK, Bye."
M is disgusted."What is he looking for, he asked, from these calls?"
I could reply, "It's a process." But don't. Better to keep some of this to myself. And to start living life.
Instead of living a life that revolves around waiting for these calls, and recovering from them.
When will I give myself permission to do so? I don't know.
