Yes, it is a Christian based book, as I am a Christian.

The first chapter is called, "What even is marriage?" And includes a subtitle of what God says about marriage in the bible, and I do include interacting with God to learn a lot of the tools or habits I go over in the rest of the book, though I try my best to focus on "WHAT WORKS" rather than Christian cliches or such.

I've noticed a lot of Christian books or teachings being quite shallow or overly "Christianese".

Our book includes a chapter on psychometric assessments to help you figure out who you are, and which type of person would be a better fit for how you function. It matters if you want an easier marriage.

Sounds like your cousin is really into dancing and would prefer a man who also likes dancing. However, it sounds like it's not the best place to find a good man, as the men who go dancing to find a lady may not be looking for a spouse 😬 so, it might be better to find a guy elsewhere who happens to also enjoy dancing. Maybe there are some of those guys here on Nostr, so if you come across one, she might be more curious about getting on Nostr 🤔😇
