Dear Bent,
1) One doesn’t support to stay in kolel for many years.
2) Feels satisfied or not is not the question. Is he growing in his learning?
3) I don’t know where to find fair in shas, but kesuba applies to non learning husbands as well.
4) Hopefully, a married woman is mature enough to tell her husband what she wants.
5) kids are not starving as much as they eat unhealthy in the USA.
