Merry meet @gigiandbrad090621 
Was it perhaps this question about sharing an altar that you found? If that wasn’t the one you found, Francisco wrote a great reply there with some advice that you might find helpful.
I also do not share an altar with my partner (who does not practice the Craft), and from what I’ve seen, I think most people tend to care for their own altars. That being said, I’m sure there are creative ways to share an altar or perhaps share your sacred room/space while keeping personal altars! Hopefully others will share their thoughts/experiences for you to consider 
Wishing you all the best, Gigi- Blessed be!
