The Talmud tells us about the relationship between Rabbi Akiva and his wife:
The daughter of Ben Kalba Savua told [Akiva]: If I betroth myself to you, will you go ... learn Torah? He said: Yes... He went and sat for twelve years in the study hall. When he came back... he heard an old man saying to his wife: For how long will you lead the life of a widow of a living man...? She said: If he would listen to me, he would sit and study for another twelve years. When Rabbi Akiva heard this he... went back and sat for another twelve years in the study hall... [Upon his return] he told [people]...: My Torah knowledge and yours is actually hers. [Ketubot 62b-63a]
We are enormously grateful for his wife's attitude, because it gave us the wisdom of a great man. But we cannot help asking: What he being fair to his wife, even though she encouraged him? Could he not have spent a few days with her before going back to study? A commentator said that 24 straight years are better for Torah learning than two sets of 12 years with an interruption in between. I am not convinced. Also, could he not have moved his entire family to the place where he was studying and have a normal family life? That same page tells us about a rabbi who went to study for 12 years and found that his wife had become infertile because he waited too long! (Another rabbi forgot how to get back home!)
The Talmud encourages scholars to be intimate with their wives once a week:
How often are scholars to perform their marital duties? Rav Yehudah replied in the name of Shmuel: On Shabbat eve. [Ketubot 62b]
Studying Torah all the time and doing nothing else is not encouraged in our tradition and the Rambam has harsh words to say about that.
Any other commentaries on that story in the Sources?
