Didnt read the question, and obviously none of the answers. the way it is presented here leads me to believe that this couple is headed to divorce in 18 months or less.
1: It was said that the husband is a night owl? What is he doing so late at night? Working? playing dungeons and dragons online (or worse)?
2: Has anyone spoken to the husband about the importance of tefilla bitzibur and tefilla bizman (I suppose it is possible to “chap” a shachris at 11am if one lives in the right neighborhood)?
3: When he finally does get up and about, does he go learn? What DOES he do from 11am till he reaches the 2nd half of the day when he starts working. What are his work hours? Perhaps he works the 3pm to 11pm shift and really IS exhausted?
The possibilities are endless.
From her side. Has SHE ever spoken to her husband about the importance of davening and how it is important to her that her husband davens bizman and with a minyan? Is she afraid to? Has she ever spoken to her husband about his nigh time activities? Unless he is working the night shift and she knows why he is up so late, perhaps she should discuss this with her husband as well?
In defense of the answers provided, the responders unfortunately are handed a question and must answer and “dont be stupid and speak to your husband before you come crying to us” is not something the editors allow from the panel. They are stuck with trite drivel. They cant answer anything else because they really dont know whats going on.
