Why the wife should be disturbed if she is living not in the association of her husband. When Caitanya Mahaprabhu went to East Bengal for preaching, his first wife was alone. Wife's duty is not to disturb the husband. That is Vedic principle. The marriage relationship is not for sex. Of course, that is the way in this age. So, such wife may marry for the second time, what can be done? Vedic marriage is not for sex.
Hoping this will meet you in good health.
