Your staying home isn't ideal, but it's much better if a dad stays home than no one at all.  Your family will benefit a great deal.  A big thing to consider is if YOU can handle it ego wise.  If you are secure enough in your manhood, then I don't see anything wrong.

The reversed marriage roles in your marriage contradict what the Catechism of the Council of Trent teaches:

Duties Of A Husband:
 
“It is the duty of the husband to treat his wife generously and honourably. It should not be forgotten that Eve was called by Adam his companion. The woman, he says, whom thou gavest me as a companion. Hence it was, according to the opinion of some of the holy Fathers, that she was  formed not from the feet but from the side of man; as, on the other hand, she was not formed from his head, in order to give her to understand that it was not hers to command but to obey her husband.

The husband should also be constantly occupied in some honest pursuit with a view to provide necessaries for the support of his family and to avoid idleness, the root of almost every vice.
 
He is also to keep all his family in order, to correct their morals, and see that they faithfully discharge their duties.”
 
Duties of a Wife:
 
“On the other hand, the duties of a wife are thus summed up by the Prince of the Apostles: Let wives be subject to their husbands. That if any believe not the word, they may be one without the word by the conversation of the wives, considering your chaste conversation with fear. Let not their adorning be the outward plaiting of the hair, or the wearing of gold, or the putting on of apparel: but the hidden man of the heart in the incorruptibility of a quiet and meek spirit, which is rich in the sight of God. For after this manner heretofore the holy women also, who trusted in God, adorned themselves, being in subjection to their own husbands, as Sarah obeyed Abraham, calling hint lord.
 
To train their children in the practice of virtue and to pay particular attention to their domestic concerns should also be especial objects of their attention. The wife should love to remain at home, unless compelled by necessity to go out; and she should never presume to leave home without her husband’s consent.
 
Again, and in this the conjugal union chiefly consists, let wives never forget that next to God they are to love their husbands, to esteem them above all others, yielding to them in all things not inconsistent with Christian piety, a willing and ready obedience.”

Also, Pope Pius XI said that the notion of the mother working outside the home without necessity is Communistic in origin:

“Communism is particularly characterized by the rejection of any link that binds the woman to the family and the home, and her emancipation is proclaimed as a basic principle.”- Pope Pius XI

Your wife needs to forget about her career and stay home with her children. As the man, it is your duty to bring home the money, as the Catholic Church has clearly taught.

Among the reasons already posted, your situation will be regretted by all involved - just give it a little time.

As a past employer myself, be assured that the first to regret it will be your employer for losing a worker, the next will be her employer for losing a worker, not only every time she become pregnant, but during her pregnancy she will have sick days she would not normally have and poor performance issues that are directly due to her condition - so her clients regret it too - and all this will place additional burdens on the everyone else in the office - then there's the 12 weeks after the birth she can be off. No matter how nice the boss may be, the list of regrets for the employer is a long one I assure you.
 
Nothing major in all of this but as a past employer myself, it was such a burden that I stopped hiring women of child bearing age altogether for that reason. It is nothing but a total and gigantic pain in the neck for any employer to deal with who is just trying to run a business. All this is really miniscule in the scheme of things, just the tip of the iceberg if you will.

Next, one of the reasons divorce is so prevalent is because of women in the workplace. Stuff happens.

Live on your salary, do your job as husband and father, not husband and mother for the sake of money.




   

The good advice here (from Mythrandylan and Stubborn) is probably going to sound harsh, but you have to remember:

God always forgives.
Man sometimes forgives.
Nature never forgives.

The concept of the MAN doing the breadwinning and the woman keeping the house and raising children is not just

My opinion
The custom of those "rad-trads"
The opinion of the Catholic Church or the Pope
etc.

but rather a fundamental element of human nature, which can only be manipulated at your peril. Nature fights back. Messing with Nature involves consequences, which some men can see, while others cannot.

As was mentioned, the enemies of God that invented Communism know just how to destroy the current order, so they can create their own "order" in its place. One of those tenets (which you can read in books or online -- their aims and goals are hardly secret) is to "emancipate" women, so they no longer need a man for anything. Ultimately they want to break up the family, and thereby destroy the current (capitalist, private ownership) society.

They want to make women dissatisfied with a life spent at home with the children. Mission accomplished in many cases, including your wife. Sorry to say, but I assume you're interested in the truth here.

I recommend you meditate on those 3 sentences:

God always forgives - You could theoretically be a stay-at-home Dad without sin, though it would be much more difficult and God probably doesn't will that for you.

Man sometimes forgives - There would probably be consequences from various human elements. But some would be OK with it.

Nature never forgives - Here is where the real hit would take place. Your children would get a bad example of proper family life, your male talents/tendencies would ultimately rebel from your position of "mother", and your wife would have similar problems.

So even if God (by avoiding sin) and society (man) gave your plan a stamp of approval, you could never hope for Nature to go easy on you.

I would also advise that you not fall into the trap of

Money = happiness

and its corollary:

More money = more happiness


It's more important to live according to nature and God's design -- that will bring much more happiness than a much of stuff imported from China, some vacations, nice cars, and a bigger house than you need.

Those things are highly overrated.

Going to Disneyland once a year with your 1 or 2 children is no substitute for daily life with your (hopefully larger) family. Look at the statistics for young people in America today. Despression, ѕυιcιdє, rebellion, etc. -- they would rather have less money and have their mother at home, acting like they are important and loved. Children instinctively know what true love is -- and isn't.

When the mom stays at home, it's not just a matter of having less money. When she's at home, there is no added cost whenever a new child is added to the family:

increased daycare costs
more lost work
etc.

Why do you think most couples today stop at 2 children?

My wife and I married long before finding tradition.  We were your typical Novus Ordo couple--and attending Mass was important, but on those rare occasions when it was just simply too inconvenient, you can imagine what gave way.  Our plans were to do as all good red-blooded Americans do:  We were both going to have our careers and let the daycare and the publics schools raise the children (though, at the time, we wouldn't have quite put it that way).

Through a coincidental series of circuмstances in our lives, the fall in which my eldest daughter would begin "compulsory education" (as if she hadn't ever learned anything before), I found my self without gainful employment while my wife had an income.  For the past 14 years I have homeschooled children.  My eldest is now a postulant in the CMRI in Spokane, Washington, I have another child graduating in May and several more on down the line.

Is it the ideal situation?  No.  My wife would much rather be home.  Is it an acceptable situation?  Yes.  It has worked.  Additionally, I know of at least three other families in virtually the same situation.  None of us actually intended that this would be a way of life, but all of us have made it work.  (One familiy in a similar situation has a son in the SSPX seminary in Winona).

I can't say that your situation will work.  But I can say that most of us (but not all) who have made it work were Novus Ordo when we began our individual situation and found tradition later.  If your wife fully embraces tradition, I believe it can absolutely work.  This, in any event, is my personal experience.  I wish you success in your spiritual and temporal lives.

The OP "planned" on having a family?

Am I misreading or misinterpreting this?
