what do you do when your husband stops believing?

Probably the best way is to just pray for him. God knows what he might be going through and why he says he stopped believing. Pray for yourself, too, that you might help to win him back by your Christian walk. Be prepared to give up more of yourself so that God can work with him.

When you have shared a faith with someone for so long and they suddenly change, it can be disheartening. We all have doubts at times but with time our faith is affirmed and we go back to our beliefs even stronger than we were. All you can do is pray and not change your attitude towards him. Do what you can do and let God do what you can’t do.

Your husband may have found a new level of comfort by not believing in a religion, he is by no means turn into a bad person in any way, he realized that not believing in a religion establishment is not the same as not believe in God, he has achieved certain enlightenment in his life so to speak... There is nothing to worry about him, and he can still be a good and caring husband to you and a marvelous human being in this later part of his life. It is not right to judge him base solely on his reluntant to go to the same old church he attended in his earlier life, it is also wrong to think those who refuse to believe in the same old religion establishment's twisted doctrine as against God teaching. Until you begin to accept these are actually mutually exclusive event, you willl know how to deal with it in due time and can seek out viable solution personally.

Maybe you should think about what he says, and what he's thinking about. Coming to a direction of not believing isn't something that just strikes you, it's something that you really have to think about, and consider possibilities. Maybe he's onto something?
