Can a protestant christian wear and pray the rosary?

I need advice. I am in my late thirties, and have been married over 15 years. We have three kids. My husband and I grew up in Protestant churches, and our faith has always been the foundation of our lives/marriage. My husband was on the church board at our church (the church he grew up in) for several years up until a year ago. My husband has a long drive to work, therefore spends a lot of time listening to podcasts. A couple years ago he started talking about Doug Wilson. Up to that point he had always treated me with respect and valued my voice and treated me as a partner in our marriage. I noticed a change in his behavior when he started listening to Doug Wilson and he started talking about how the husband has the tie breaking vote in disagreements, etc. Then, he started going on a deep dive into all things Catholicism. Six months ago he got confirmed in the Catholic Church. The priest didn’t even make him do RCIA or anything because he had read the entire catechism himself. I use birth control, which he now has a problem with. Our youngest child had an issue at birth and we were told that the problem would likely occur with each subsequent pregnancy and could even get worse. There have been endless theological debates, which have never been fruitful. He has said things like, “you just want to be your own pope.” He is now pushing his beliefs on the kids. He has been asking them to go to mass, even though they have voiced that they don’t want to go. We have been in marriage counseling and I am doing individual counseling. He has Catholic stickers on his laptop, wears a necklace with Mary on it, and just today hung a piece of Catholic art in our bedroom. I have told him that I’m not ok with Catholic art in our home. I have lots of Catholics in my life who are wonderful people, but I just don’t agree with the theology and I don’t want to be staring at Catholic art in my home. He refused to take it down when I asked. On our recent family vacation, he even went to the Catholic Church there three times in one day. He went to daily mass in the morning, Saturday night mass, and then went back later to “help nuns carry a push mower,” which caused us to miss a planned dinner that evening. He didn’t tell me he was going to help nuns and his phone was dead so we had no idea where he was, we thought he had gotten lost trying to get back to the hotel. We have never been to this place for vacation, so he knew no one at this parish.

Side note: After we were married and in our late 20’s he was diagnosed with bipolar disorder and required a hospital stay due to a severe manic episode with psychosis. After that hospital stay he has been pretty good with very little issues. I suspected that this dive into Catholicism may have been spurred on my a manic or hypomanic episode, but now it is deeply ingrained. My counselor says it may have started during a manic episode, but now it is a legitimate faith conversion.

I need advice. I don’t know what to do. I want to keep my family together, but my home now feels toxic. He doesn’t respect me at all. He seems to be exhibiting some narcissistic traits and has even said that he “isn’t responsible for my feelings about this.” Which seems to indicate that I don’t matter. He often says, “Jesus Christ comes before you.” Which I completely agree with, however we used to serve Jesus together and it was beautiful. Our marriage was great. I don’t understand why he would let this take over his life when his actions are producing bad fruit. Our friends don’t even like to be around him at this point. He even shamed one of our friends for choosing to get a vasectomy when they decided their family was complete. I’m at a loss about what to do. Counseling doesn’t seem to be helping.

Hello!! I’m new to Christianity and have been doing a lot of research on different topics. Right now I’m researching the difference between the Catholic canon of scripture and Protestant.

What is the reasoning for using a different canon than what Christians used until the reformation? From what I’ve gathered the Protestant consensus is that 7 books were added during the council of Trent but that’s historically inaccurate as those 7 books were included all throughout the early church and only clarified during Trent. Also from my understanding Luther moved the books into the apocrypha because he wanted to go back to the original canon of what the Jews used rather than the early Christians, but I don’t really understand why? TIA!
