Śrīmad-Bhāgavatam (5.5.18) states, na patiś ca sa syān na mocayed yaḥ samupeta-mṛtyum: “One cannot be a husband if he cannot liberate his dependents from inevitable death.” If a person is not in Kṛṣṇa consciousness and is bereft of spiritual power, he cannot protect his wife from the path of repeated birth and death. Consequently such a person cannot be accepted as a husband. A wife should dedicate her life and everything to Kṛṣṇa for further advancement in Kṛṣṇa consciousness. If she gives up her connection with her husband, who abandons Kṛṣṇa consciousness, she follows in the footsteps of the dvija-patnī, the wives of the brāhmaṇas who were engaged in performing sacrifices. The wife is not to be condemned for cutting off such a relationship. In this regard, Śrī Kṛṣṇa states in Śrīmad-Bhāgavatam (10.23.31-32):
patayo nābhyasūyeran
pitṛ-bhrātṛ-sutādayaḥ
lokāś ca vo mayopetā
devā apy anumanvate
na prītaye ‘nurāgāya
hy aṅga-saṅgo nṛṇām iha
tan mano mayi yuñjānā
acirān mām avāpsyatha
Such a separation is never condemned by the supreme will. No one should be envious of the order of Kṛṣṇa. Even demigods support such action. In this material world, one does not become beloved simply by maintaining a bodily relationship. However, one can attain complete perfection by associating in Kṛṣṇa consciousness. When a husband is fallen, his relationship must be given up. This is a quotation from smṛti-śāstram. As stated in Śrīmad-Bhāgavatam (7.11.28):
santuṣṭālolupā dakṣā
dharma-jñā priya-satya-vāk
apramattā śuciḥ snigdhā
patiṁ tv apatitaṁ bhajet
“A wife who is satisfied, who is not greedy, who is expert and knows religious principles, who speaks what is dear and truthful and is not bewildered, who is always clean and affectionate, should be very devoted to her husband who is not fallen.”
