But what do you make of the argument?
I think it's really bad advice, for so many reasons!
First, if you have a satisfying and challenging career, do you even
need a husband? Gone are the days when women couldn't own property. You don't need a man to put a roof over your head any more. You don't even need a man to have kids.
So given that women can independently obtain anything that marriage used to be expected to deliver, there is only one good reason to get married: you want to spend your life with sometime who wants to spend their life with you.
Young people are too inexperienced and foolish to get that right, IMO. Several of my relationships when I was younger drifted to talk of marriage greater levels of commitment (like living together). That's because we were on auto-pilot, behaving in accordance with society's expectations. Not because we really wanted to spend our lives together. All it took for me to come to my senses was to really ask myself honestly if being with this particular guy was better than being single. In every case but one (the man I married), it wasn't.
Over half of the women I know who drifted into marriage and kids in their twenties are terribly unhappy, and so are their husbands. The exception would be those who have divorced their first partner and found a more compatible partner or decided to fly solo.
People who marry later in life have a far lower divorce rate, and IME those who have kids are far better equipped to deal with the financial burden and the stress.
As for having to compete with younger women, pffffft. Who wants to be with a man who is into immature little girls with college debt and no jobs? Most men these days want a
partner. An emotional, intellectual and professional equal. If a man
doesn't want that, you don't want him. It's a recipe for certain misery.
I genuinely feel sorry for the author if she thinks her marriage is the primary source of her happiness. Her life so far must have been very dull , confined and unimaginative. And talk about an unfair burden for your partner - making them solely responsible for your life satisfaction! No wonder so many marriages end in divorce.
