If your H modeled his M after his father's M, do you have fears that your S may someday have the same attitude?
Some men are too career oriented. I can think of 2 American frontiersmen - Daniel Boone and Davy Crockett that would periodically abandon their family to pursue adventure. It has been said that Daniel Boone's wife of 57 years once thought him dead and developed a relationship with his brother which resulted in a birth of a daughter. Upon his return, his wife said "You'd had better have stayed home and got it yourself.". Boone was understanding and did not blame her. Whatever the truth of the tale, Boone raised the daughter as his own and favorite child.
Can you accept that your H's work is in his blood and takes much of his time?
