K.N.
I was the "dad" you speak of: I worked unreasonable hours as the primary breadwinner in our family (and for those who believe their breadwinners choose those long hours, I have a very different perspective. Knowing your family relies on your paycheck to pay the mortgage is a considerable weight). My husband was usually home by 3:30 every afternoon. If I worked 50 - 55 hours a week, it was a good week!
Still, I made sure I connected with my kids. I was the one who kept on top of the school work and in touch with the teachers. When I was home before they were asleep (most nights, thankfully), I handled the bed time routine and the story-reading. When I travelled for work, I called home every day and would some times carry a copy of a favorite bed time book & read it to them from the road. I remember once waiting for a flight in Miami airport, reading to them & getting very strange looks (and, honest, I had stepped away from the crowd & kept my voice down -- I think it's hugely rude to force your phone conversations on others).
The point is, regardless of gender, a parent is a parent -- and as committed to their children and their marriage as they choose to be. It can be difficult when you're working like a crazy person, but with some help (and sometimes some suggestions from the one more often at home), it can be done.
