myfreind, while a Torah lifestyle is a beautiful life for those who can live it, such a life is not a chiuv for those who can, because the Torah was not given to angels and we each have our own paths in avodas Hashem.
One however, cannot expect a husband to simply ask a wife what is bothering her if he suspects that she is unhappy with her current lifestyle. If he needs to go out to work he’ll be unhappy. So it’s highly unlikely he’ll ask her what’s bothering her, especially if he knows what the answer will be. Whether it’s right or not the husband should be the one to initiate a conversation about this is beside the point. It’s unrealistic to expect that.
If the wife or husband wants to discuss something, they need to be mature and start the discussion, not hope that their spouse will pick up on their unhappiness. Because chances are, they’re going to ignore it.
