| Dear Carolyn: We have two friends we’ve known for over a decade. They recently separated and are getting a divorce. He moved out two months before the oldest child graduated from high school with what we perceive as no warning. Neither of them will tell anyone why they’re getting divorced. When we’ve asked them individually, or other people in the friend group have, they just say they don’t want to talk about it. It’s really awkward hanging out, since it’s a giant elephant in the room. To be married for 20-plus years and then just stop? We wonder if we ever really knew these people to start with. What do you think would be the best thing to do? — You’re Really Not Telling Me? |
