Some marriages are not healthy and divorce is a good choice, a safe choice. Unfortunately, many others end in divorces, too, marriages that could have thrived again. Or they continue as pretense, for the kids, for the shared property, for the lack of financial options, even though they could have returned to loving, sharing, trusting relationships.
If you’re not in immediate threat of death or grave harm, knee jerk responses to a husband’s or wife’s actions that upset you or disappoint you or frustrate you will probably be the wrong ones. Give your next step some thought. You might save a great marriage. And that always beats starting over with someone new.
