It sounds to me like you are asking whether it matters what you say or do.
IMHO it does not matter, except with YOUR detachment.
If you can remain detached with no expectations then nothing you say or do is going to make his crisis go any faster. He will stop being depresses when he CHOOSES to. Likely a long time from now. However if what you are doing continues to keep you attached to him then you are prolonging the PAIN and I suggest you 180 that.
