I reached out to a friend I hadn't spoken to in a couple of years after she did this. Sent her a private message. She said she's divorced and when I asked if she's OK and how the kids are getting on, I got ghosted.
Also got another guy friend who I offered support when he was going through a real rough patch with his wife. He told his wife to tell my wife to tell me that he doesn't want to talk.
I guess people don't want to talk about it.
