I am a product of a Catholic-Protestant marriage. Before Mama and Daddy married, she had to promise to raise any children they had in the Catholic Church. She had no problem with it and now in the winter of her life, is Catholic.
If your Protestant wife has given her consent for you to have your children baptized Catholic, do it. It would be nice if she fully supported your conversion and your desire to raise your children in the Catholic Church. But it’s evident that she doesn’t since she doesn’t want you taking the children to Mass
Can you find a compromise? In my case, Mama took me to Mass. And when we moved here, I attended Protestant churches while she tried to find the nearest Catholic Church to us.
After Mama found the parish we now call home, I was able to attend the Early Mass on Sundays and then attend Protestant services down the street. I never gave up being Catholic. But attending Protestant services as well gave me the perspective of both sides.
Perhaps you can appease your wife by allowing your children to attend services in her chosen denomination as well. And when they are older, they can decide whether they wish to be Catholic or Protestant.
I also suggest you speak to your priest about this. He may have other suggestions for resolving your dilemma.
