The single most important ingredient in marriage is RESPECT. Respect means finding a place in your heart to host the feelings and needs of another person.
A true story: A man divorced his wife, who was a very prominent educator, endowed with many talents. Two years later he remarried a woman who seemed very unimpressive - intellectually, financially and emotionally. He claims that with his new wife he became a happy and satisfied person.
"My ex-wife is superior to my present wife in all respects, a better person, smarter, more balanced..." BUT? "My second wife - believes in me! I am not perfect and she always gives me a chance. She doesn't count, like my ex-wife, the minutes until I disappoint her once again."
