Krishna is the real husband of all living entities.

“Laksmidevi (Rama) shows compassion toward women who worship the Lord for the benediction of possessing a good husband. Although such women desire to be happy with children, wealth, a long duration of life and everything dear to them, they cannot possibly do so. In the material world, a so-called husband is dependent on the control of the Supreme Personality of Godhead. There are many examples of a woman whose husband, being dependent on the result of his own fruitive actions, cannot maintain his wife, her children her wealth or her duration of life. Therefore, factually the only real husband of all women is Krishna, the supreme husband. Because the gopis were liberated souls, they understood this fact. Therefore they rejected their material husbands and accepted Krishna as their real husband. Krishna is the real husband not only of the gopis, but of every living entity. Everyone should perfectly understand that Krishna is the real husband of all living entities, who are described in the Bhagavad-gita as prakrti (female), not purusa (male). In Bhagavad-gita (10.12), only Krishna is addressed as purusa:

param brahma param dhama pavitram paramam bhavan
purusam sasvatam divyam adi-devam ajam vibhum

“You are the Supreme Brahman, the ultimate, the supreme abode and purifier, the Absolute Truth and the eternal divine person. You are the primal God, transcendental and original, and You are the unborn and all-pervading beauty.” Krishna is the original purusa, and the living entities are prakrti. Thus Krishna is the enjoyer, and all living entities are meant to be enjoyed by Him. Therefore any woman who seeks a material husband for her protection, or any man who desires to become the husband of a woman, is under illusion. To become a husband means to maintain a wife and children nicely by supplying wealth and security. However, a material husband cannot possibly do this, for he is dependent on his karma. Karmana-daiva-netrena: his circumstances are determined by his past fruitive activities. Therefore if one proudly thinks he can protect his wife, he is under illusion. Krishna is the only husband, and therefore the relationship between a husband and wife in this material world cannot be absolute. Because we have the desire to marry, Krishna mercifully allows the so-called husband to possess a wife, and the wife to possess a so-called husband, for mutual satisfaction. In the Isopanisad it is said, tena tyaktena bhunjitha: the Lord provides everyone with his quota. Actually, however, every living entity is prakrti, or female, and Krishna is the only husband.

ekale isvara Krishna, ara saba bhrtya yare yaiche nacaya, se taiche kare nrtya (Cc. Adi 5.142)

Krishna is the original master or husband of everyone, and all other living entities, having taken the form of so-called husbands, or wives, are dancing according to His desire. A so-called husband may unite with his wife for sense gratification, but his senses are conducted by Hrsikesa, the master of the senses, who is therefore the actual husband.”
