If you google common reasons for divorce, you will get the following major causes:
- Poor communication
- Financial problems
- A lack of commitment to the marriage
- A dramatic change in priorities
- Infidelity
- Failed expectations or unmet needs
- Addictions and substance abuse
- Physical, sexual or emotional abuse
- Lack of conflict resolution skills
My own marriage of 30 years failed for 8 of the above 9 reasons. My ex is not TG. I suspect that when a marriage that involves CDing fails, it is because there are quite a few of the above issues present as well.
There is only one cause above (the dramatic change in priorities), which might describe the CDing. But, a partner can CD and let his wife know their marriage and family life is still very much a priority.
