My ex would never have ended our marriage, although I can't believe he'd describe himself as "happy" when I, his wife, was seriously depressed year after year. But he was capable of being utterly oblivious to how I was feeling. Once we were at his parents' house and I was suffering from a stomach flu and was obviously sick and feeling wretched. His father told him to take me home, and he said, "Oh, she's having fun." It was so outrageous it actually made me laugh and became a kind of punchline between us -- but it was a sour sort of laughter.
