My FIL is not a bad father or role model, let me say, but instead is a man whose values are quite different from my own. He is a very very successful man, famous and prominent in his field, constantly appearing in the newspaper, on the radio, and even on TV, and he is a workaholic. He was rarely home for dinner, he traveled at least 1 week a month (not required for his work, but optional) as they were growing up, and now travels at least 3 weeks a month, and he likes to go into work on holidays to see which of his subordinates are dedicated enough to come in on holidays (they go up in his esteem if he finds them there!). To him, raising children on the day-to-day is a woman's job.
He raised his 3 sons to believe that their accomplishments in their careers basically defined them as successful. Success in family life if he was not climbing the ladder at work was not success at all. All 3 boys are well-educated and hard workers, and all 3 get a lot of their self-esteem and fulfillment from their work. However, my wonderful husband is also a fantastic family man, and he has his priorities in order. He is home for dinner almost every single night, because he believes that he should be actively involved in his child's upbringing. He helps me take care of our son as a partner, and although his job sometimes requires long hours, he does everything he can to spend as much time with us as possible, even working from home sometimes so that he is always home to put his son to bed. My husband does not see this as defeating his father's legacy (he thinks very highly of his father), but instead as being true to his own values. Your husband can do it, too.
