I believe you did the right thing though I’m terribly sorry that you are facing this.
I do have a suggestion though. In the New Testament we find passages that mandate that wives obey their husbands out of obedience to Christ, and, having been active in both Baptists and Assembly of God I know that this is a big deal to them, so please pray about this and then print out and give her these scripture references.
1 Peter 3:1-22
Colossians 3:18-19
1 Timothy 2:12
Galatians 3:28
**Ephesians 5:21-33
**Now it’s important you do this with all the charity you can muster, okay.
You must firmly tell her that effective right away that she is to be obedient to you as her husband even if she thinks you are not a Christian because you are Catholic. She may see herself as “unequally yoked” with you, but that’s no excuse (See 1st Corinthians 7:13-14) and that you forbid her to badmouth the Catholic faith in any way, either in public or in private and that she must remove every social media post she has that does so. Tell her that this is exactly what the Bible mandates for married couples and that if she calls herself Christian then this is the way it has to be.
Tell her that you will also abide by all that the New Testament commands for a husband in her regard.
Be sure to look up all of these scriptures and print them out so you both have a copy so you know where you stand. You will need to assure her of your love for her and that these are the scriptural standards for your marriage.
It may be difficult but this is where you make your stand in order to save your marriage and (God willing) win her over. There is no “wiggle room” in this…this is what the Bible teaches. Period…
Be loving and kind in every way, but be firm about this because your faith and your marriage hang in the balance.
Rest assured of my constant prayer support.
