We might get the impression that once a spouse decides they want a divorce, the move to the end the marriage quickly becomes the certain choice of both partners. By the time the divorce is finalized, both partner's are likely confident about the difficult choices they are making.

The Doherty Institute released this video addressing research that points to the uncertainty that some couples continue to feel about the choice they are making. Is it too late for those couples to give their marriage another chance?

Marriages sometimes end for legitimate or necessary reasons, but one reason often presented for divorce is the idea children should be witness to a happy marriage. The argument goes something like this: If the marriage is no longer a "happy one" then perhaps the kids would be better off if their parents found a more fulfilling relationship.

This new video from the Doherty Relationship Institute provides a perspective on the issue.

​We usually expect our marriage to last a lifetime. What starts with promises of faithfulness and endurance, we believe, will survive any challenge "for better or for worse." Most marriages do; some even thrive. But many die in ways never anticipated.

​When the death of a marriage is a mutual choice between two partners, grieving its loss may be a short-term process. The decision to end their relationship often follows a period of prolonged suffering, making divorce feel like relief. Similar to a funeral, partners make the appropriate arrangements, pay their final respects, bury the marriage, and move on with their lives.

But a marriage killed by betrayal is not so easily mourned.
