I will repeat what I said before:
The word for marriage in hebrew is Nisuim to elevate, that is to put each other on a pedestal and only see good in each other. When loving each other, each partner is willing to accept criticism to improve each other spiritually.
I lost my wife around 8 years ago. When you become old and children are married off, there is someone who takes care on the other. Living together without marriage is goyish.
