have you read all of the posts and threads from Did?
He needs to close down communications with his W. His W will see this response, even if only addressed to his daughter, as pursuit. It's his face going to his W's phone. It's temptation for Did to pursue. Did does not need temptation because he is an a delicate emotional state. He is a good man going through a hard time.
Plus, Did needs emotional space right now. He's wound up tighter than hell and interacting with his W is the primary reason why. She knows how to pull his strings.
Did, please don't respond to your W's facetime. It is your W, not your daughter calling.

It is not things that bother us, but the stories we tell ourselves about things.
