They’re not married yet, thank God. Otherwise your advice is good.
Oh… reading is fundamental, I see. Well, Juliane and 1ke have given good advice too. This is, as we say, a huge red flag for you. Agreement on how to raise the children is such a basic and important element of a marriage that practically everything else will depend on it. Remember that when we marry someone, we don’t just marry a woman, we marry into a family. If half your family is non-Catholic, and any of them are at all observant in their faith, you will experience enormous pressure to produce the children that they want, rather than the children that your wife and you want. It is unavoidable, so in choosing any mate, always consider her family, see whether they are deeply involved in her life or estranged from her. Determine for yourself if you have the wherewithal to take a stand. For a Catholic husband this should be a matter of the utmost importance: we want to raise children in the faith and carry on after we are gone. There should be no caving or compromise in this matter.
As a faithful Catholic man, you deserve a wife who will lovingly raise children in your faith. Don’t settle for less.
Let me suggest that you seek out a spiritual director and ask for his help as you discern your vocation to married life. Many people think that a SD is only for vocations to the priesthood or religious life, but I think a SD can help adults in their spiritual journey wherever we are headed. I am seeking one now because I am over 40 and still no vocation at all. I want to rule out vocations that I am not suited for. Perhaps I am still called to marriage, it is not out of the question at my age. But I can tell you that I wish I had had a SD 5 years ago when I foolishly asked a woman to marry me. Red flags were already showing themselves in the months we had known each other online, but we got involved, met the parents, and started planning for a wedding, all in the space of two weeks after meeting for real. Well, it was only after a disastrous trip to Spain that she realized that perhaps I was not for her, and it was only after two more breakups with her that I began to realize that she was definitely not for me. She was a convert to Catholicism and yet she believed in nothing the Church had to offer. She rejected the authority of the hierarchy, the efficaciousness of Penance and Eucharist, and she rejected teachings on sexual ethics, marriage, abortion and contraception. Imagine how
messed up our children would have been! I got out with my soul intact but the instances I put myself into grave sin because of her weigh heavily on me even now.
Don’t let your love for a woman blind you to the realities of incompatibility. Get objective, unbiased advice and look at your relationship under a microscope before you make any decisions. Good luck, we are praying for you.
