Answer:
Mathew is a companionable husband in the sense that he assisted his pregnant wife in her search for the antique cradle, despite the fact that neither of them knew where to look. He agreed despite the fact that it was a foolish demand. He gladly agreed to his wife's request because he wished to be a good husband and father. It didn't matter to him if he didn't know where to begin; what was important was finding the cradle. He's the type of husband on whom his wife can rely.
