My ex-wife and I have an agreement that we don’t talk about our marriage and divorce in public. But when I look back generally on the errors and failures and sins of my life, they tend to be failures of omission, failures to truly show up for the people I should have been close to. They tend to be the sins of withdrawal: evasion, workaholism, conflict avoidance, failure to empathize, and a failure to express myself openly.
