This is a widespread problem in our culture, it’s certainly not isolated to Catholics. My protestant friends talk to me about members of their families who refuse to accept faith. Even while these marriages stay together and may be considered successful, I believe it’s due to 1 of the 2 in the marriage persons remaining devout to faith
I can tell though in almost each case, the person of faith feels a deep disappointment in that the person they most love doesn’t share what’s most important in their life. That being the love God.
You’re very blessed at a young age to have kept the faith. I know very few of my friends that have. There’s nothing you can do, it’s entirely up to him to listen and hear the call of the Holy Spirit. What you have to ask yourself is how important God is to you and your future marriage and family.
For me personally and maybe others beyond 40, if I were given a chance to do it all again, I would have definitely sought a person of faith, particularly the Catholic faith . The Catholic faith , so long as you stay true, will be the only thing that will remain with you your entire life, even until death.
