A husband need love his wife like Hashem love Israel - as a bridegroom loves his bride:
...
[as] the bridegroom rejoiceth over the bride, [so] shall thy God rejoice over thee. (Isaiah 62:5)''Thus saith the LORD, In an acceptable time have I heard thee, and in a day of salvation have I helped thee: and I will preserve thee, and give thee for a covenant of the people, to establish the earth, to cause to inherit the desolate heritages; That thou mayest say to the prisoners, Go forth; to them that
[are] in darkness, Shew yourselves. They shall feed in the ways, and their pastures [shall be] in all high places. They shall not hunger nor thirst; neither shall the heat nor sun smite them: for he that hath mercy on them shall lead them, even by the springs of water shall he guide them. And I will make all my mountains a way, and my highways shall be exalted. Behold, these shall come from far: and, lo, these from the north and from the west; and these from the land of Sinim. Sing, O heavens; and be joyful, O earth; and break forth into singing, O mountains: for the LORD hath comforted his people, and will have mercy upon his afflicted. But Zion said, The LORD hath forsaken me, and my Lord hath forgotten me. Can a woman forget her sucking child, that she should not have compassion on the son of her womb? yea, they may forget, yet will I not forget thee. Behold, I have graven thee upon the palms of [my] hands; thy walls [are] continually before me. Thy children shall make haste; thy destroyers and they that made thee waste shall go forth of thee. Lift up thine eyes round about, and behold: all these gather themselves together, [and] come to thee. [As] I live, saith the LORD, thou shalt surely clothe thee with them all, as with an ornament, and bind them [on thee], as a bride [doeth].'' (Isaiah 49:8-18)''I will greatly rejoice in the LORD, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness, as a bridegroom decketh
[himself] with ornaments, and as a bride adorneth [herself] with her jewels.'' (Isaiah 61:10)''For thy Maker
[is] thine husband; the LORD of hosts [is] his name; and thy Redeemer the Holy One of Israel; The God of the whole earth shall he be called.'' (Isaiah 54:5)In the Jewish tradition love to wife has an important role.
A husband and wife must be together.
