Affirm her feelings of loss and difficulty. Yes, it will be a challenge, but you will both find joy in respecting each other’s conscience. You will be a better husband, more at peace and more loving.
I had some heated discussions about theology with my protestant husband. My priest advised me to stop those discussions for now. ‘Just let him see the changes in you’.
As far as the articles she throws at you: calmly tell her there are answers to all those accusations, in many different places (Catholic Answers, Call to Communion, the catechism, Scott Hahn books…) but you’re not going to fight about it. If she wants to know, and not fight, you’re willing to peacefully discuss.
I like to calmly tell my protestant friends (who may or may not believe I’m crazy) that I discovered there’s not only answers for questions about catholic belief… but seemingly endless answers! It’s all there, and has been expounded upon in every age, for the last 2,000 years!
