Career is important, my family and I have certainly enjoyed the fruits of my labor. But it pales in comparison with family. One of the things my wife said to me during the bomb conversation sticks in my mind. When I told her what a financial hit it would be for us to live separately, she said "I'd rather be poor and happy."
Like you, I thought that providing was the main part of being a husband and father. That's actually just the beginning. I've allowed the pressures (or at least how I handle them) of my job to endanger my marriage. If I lose that, and the odds are pretty much against me, all that career nonsense will have been for nothing.
Keep your marriage first!
