Here is the reason why.
When Lord Shiva and Gauri become ardhanarishwar, Lord Shiva had Gauri come to his left, because the left side is the man's "better half" or his Shakti.
Wife is considered Ardhangini; Wife is the VAMANGI. i.e. the left half of the GRIHASTHA. The left side of the husband indicates the Chandra nadi (Moon channel).
Heart is on the left side of the body, and wife is the heart of her husband. So many things has this inner meaning, before tying the mangal sutra the woman was made to sit to bridegrooms right and after that she will be in his left always.
A wife sits on her husband's left side at the time of donating vermilion (Sindoor) making a re-entry after marriage or gona' taking meals, and while serving at the time of seeking blessings, wearing clothes, rinsing feet of the Brahmins.
At the time of marriage of her daughter, installation, sacrificial, and other religious rites the wife should sit on right side of her husband. Similarly, the wife and the son should remain on the right side at the time of performing ceremony on the birth and at Naam of the child, while consuming food and making an exit.
The meaning changes only in the case of polygamous marriages. When a man has more than one wife, the first wife stands to his right, because his shakti is divided up between all wives, and the second, third, fourth and other wives stand to his left.
