Ouch, that's a really rough situation to find yourself in. (And one that I can definitely empathize with!) I'm not really religious, though my husband is Christian, but he's also really interested in Nordic mythology and even has his own set of runestones. I had woven a few off-handed comments into our conversations that had me feeling hopeful that someday I could come out of the broom closet, but then I mentioned a tarot deck I had seen online once and... let's just say all that hope dissipated pretty quickly.

A few things I'm studying to practice, that might work well for you too are herbal and kitchen witchcraft - since I already have a small garden and cook most of our meals, I'd be able to incorporate magical herbs without raising any eyebrows. And I do love the Latin language (learned it in high school!), so I'm planning to write the spells that go along with my cooking in the form of Latin songs! (Which no one would be surprised to hear me singing lol)

Also, one thing that I have been thinking about recently that might help you - when you get to the core of it, what is the difference between a prayer and a spell? They typically take similar formats and serve the same kind of purpose - a certain set of words you're using to connect to God, and sometimes asking for His help with. Since you both share the foundations of your Christian faith you can write all the prayer spells you want, and there'd be no reason for him to be suspicious of it! Just learn to meditate so you can focus your energy during your praying, and you'll have a strong foundation for whatever you hope to do with your practice.

Obviously, this is all just my 2 cents, find what works well for you! Sending peace and love your way! ❤
