This question is a matter of personal opinion so let me give you mine. I believe that a man's wife is more important than his mother, for the simple reason that she's the one that he spends the rest of his life with. His mother will always be there, but she's not the one who's going to give birth to his children, she's not the one that's going to take care of them and breast feed them when they're young, that's the job of his wife.

Besides, when you get married to a woman, she leaves her family and becomes a part of yours, in a way both of you leave your families and start a new family together. If any man chooses his mom over his wife then that means that he chooses his mom over his kids and basically his own family as well.

In my opinion, the wife is more important than the mother after marriage.
