My brother's getting a divorce

[Mr.Obvious]

Hey,

My older brother told me he was getting a divorce yesterday. I didn't see it coming. He's usually a quiet man, not talkative, and he wasn't yesterday either. Though it was clear he was distraught and broken up about it. They've been married for about 4 years, but were together for 13 or so, I think.
I didn't know what to say or do. I feel horrible that he is going through this. And I want to show him he's not alone in this. I hugged him, which is something we don't often do. We are both a bit reserved on that front. But I just... I don't want him to be going through this. He's this kind and quiet guy that really doesn't deserve anything bad to happen to him. And I'm just powerless to do anything. I'm going to try and be there for him. Spend more time with him... But I don't know what I can do. I feel helpless in his stead.
Anybody got any sage advice? Do I try to get him to talk about it? Do I try to get him not to talk about it and get his mind of things? Should we go out to a pub so we can converse or rather do an activity so we can get him to focus on something else... I don't know where to start.

Also, I wrote this poem about it. But no, I'm not going to show him that. It'd be awkward.

The Undertow
Your tranquil waters offer no more solace,
as I can’t help but ponder and wonder
at this river of blood beneath the callus
of where your heart was ripped asunder.
I can’t fathom the leagues it must stretch
and clad in darkness the fathoms below.
Here I stand on the silver shore’s edge;
captivated by the pull of your undertow.

You and I were carved from selfsame flesh
so I feel  your muscles and know your bones.
My body calls out to yours begging to thresh
for I’m sure you can swim coated in stones.
That kicking and thrashing I know you can.
Struggle, I no longer wish to see you tranquil.
Swim, you wonderful bastard, you fine man.
Don’t you dare let those waters turn still.
