There’s nothing stopping you from attending RCIA, growing and living your faith. Of course the fullness of all the sacraments await, but not yet.
I’m thinking this… if you don’t go to RCIA, you won’t learn about the faith, your husband will breathe a sigh of relief maybe, and the status quo will be the status quo.
If you DO go to RCIA, you will learn about the richness of the faith, how to pray with a deepness you’ve never experienced, experience Jesus (if not in the sacraments, you can still spend time in the Blessed Sacrament as MUCH as you want) You will also show your husband and others how big your faith is. Don’t let anyone deter you from growing in holiness. Yes, it’s true, you will have to go through some things before you can receive all the sacraments, and your husband will have to go to confession, you’ll have a period of “difficulty” while you await your marriage being regulated, but it’s worth it.
I taught RCIA for years, and there was a woman and her to-be-husband for THREE years attended, and persevered. I attended their wedding, and her sacraments. How wonderful it all was…
Praying for you to have extraordinary perseverence and a supernatural faith, and for your husband’s heart to soften…/
Bless you.
