Why do unhappy spouses stay married to each other?  Like the Lion in the Wizard of Oz, they lack enough courage to divorce.  Researchers surveyed 2,000 unhappy couples and found 10 reasons why they just don't go their separate ways:

1. Lack of courage

2. Possibility of regret

3. Hope of improvement

4. Impact on the family

5. Lack of financial security

6. Unwillingness to sell the home or move

7. Too old

8. Feeling of guilt

9. Intimidation of being on their own

10. Being lonely
