After phone coaching session #2

It's not really a talk to change anything unless he says No Way Am I Paying For That.

It's a talk to include him in the process.

How can he improve his parenting interactions if he's not included?

I agree, in fact if you bring this up, it really has little to do with your fears about the situation (poor wording on my part) but your concerns about how difficult it may be on him. That way you encourage him to share any worries he has. Be supportive of him, not ask him to be supportive of you.

Whether you bring it up or not is something you can judge better than us. But there'll be other opportunities for this, if this situation is not appropriate.
