Well, he converted to Islam but for you. So he started out with faith in Allah swt. Somehow…you’ve made it go away. I hate to be so direct but its true. His issue is with how you’re forcing him to do things.
He doesn’t like the way you show him Islam…you’re the closest thing he has to a guide and your method of bringing him to Allah swt is wrong.
You cannot force anyone to do anything…its **not **your right or place.
And furthermore…when you married someone who converted to Islam…you knew what you’d be getting into. He is not a born Muslim…he will have to understand things on his own. So why is his faith an issue now?
