I think we all can name shihans with complex personal lives. But then, we can probably name professional athletes, writers, and musicians with equally complex lives. And we can all name people in all those categories who are good parents, devoted to their spouses, and generally exceptional human beings.
Based on my own experience, though, if your marriage will fall apart because you do something you love three times a week instead of two, there are probably other issues there that have nothing to do with aikido.
I appreciate your statement. It respects the contribution of personal responsibility in a person's own life. I think this is a soft-life skill that is important for being successful in any area of your life.
