In bed one night, my husband told me, “I talked to Dave today. He and Chloe are getting divorced.”

The last time we saw Dave and Chloe, they were the picture of a happy couple. We’d shared a pizza and beer, talked about the vacation they’d just taken and how they wanted to have kids but weren’t sure when. Maybe my husband and I were also the picture of a happy couple, holding our three-month-old baby, joking about how tired we were. Two couples in our thirties, with our easy smiles and glasses of wine, arms slung causally around each other, happily married.
