They're just used to it. They're just used to it. When people hear someone crying very often and are really incapable of doing anything about it, they just turn off. There comes a point where the tears no longer arouse their compassion, and they respond with indifference. It is human nature.
Husbands also react according to the rules of human nature.
If you overload his circuits and swamp him with worries and problems that he is incapable of handling, and if you do this often, he will inevitably shut off that wonderful sympathetic ear of his and become like those people from the shul walking right past the weeping man. And this would be a very bad thing, both for you and for your husband. The lines of communication must be kept wide open in order for your relationship to flourish and deepen all the time. So that is why I was saying that you should use your special wisdom to decide what, when and how you should tell him your problems. I'm not saying you should hold anything back from him.
