If you can't balance the two, then you aren't a complete man yet.
Most of the people here, who are commenting aren't even married yet, so they are assuming ditching the wife is glorious work.
The Quran says "Heaven lies under the feet of the mother".
The Quran also says "Children have a responsibility towards their parents especially mother and father."
So why should your wife bear the brunt of your mother's criticism or cook for her and do everything in the house for your mother, while you slave away at work, to bring something for your wife?
Infact, in Islam, it's YOUR DUTY (not the wife's duty) to give food and all the favors to your mother.
Desi people have a shameful mentality, that after getting married, just tell the wife "This is my mother, respect her, for she is my mother, and do everything she tells you to, because she is my mother".
Why the hell should she respect your mother, when you haven't respected the woman you are marrying to the equivalent degree.
More could be said on this topic, and it wouldn't be enough.
However, gradually you find, both of them are important in your life, and you balance them out.
And it takes a complete man to learn how to do it. A beautiful journey into relationships and how they should be managed in life.
Not an immature teen claiming mother is best, or another immature man , thinking about stepping into a relationship with all the eggs in mother's basket.
