Not sure if it's my place to "do" something.
He's a married man, middle aged, I know him through a hobby group. He's talked to us (the group) a few times about how things aren't great in his marriage, but he really hopes to be able to sort things out. I don't ask questions or pass comment, listen when he wants to talk, wish him well in his efforts. I genuinely do hope they can resolve things, that's what he wants.
Today he told me he's thinking of buying a van and disappearing. He turned it into a joke when I expressed concern, but if it was a joke he was only half joking iyswim.
I feel like I should check in on him, but I'm also very aware that having another woman fussing over him is very unlikely to help his marriage.
WWYD?
