When one person doesn't feel their spirit is being fed.

What do scriptures say?

We can dream up all sorts of should-haves, but in the end it is their decision, and they need to make it work.

We can't assume that every marriage and every partner is neatly devoted to Christ and running smoothly. Her decision to go where her husband needs to go, might be based on her knowledge that he will not attend church unless it is there.

It sounds like she has hit a point where she really does need to get involved somewhere else. It doesn't have to be Sunday, though -- she could attend side events like Bible Studies and creative worship meetings.

Separate churches can work if she approaches it with sensitivity. Just asking if he would mind if she went to see what that church was all about. She will know how to handle it better than anyone else.

I know couples who attend separate churches, and have done this temporarily myself. It is not a horrible offense. It does not in itself divide a couple. It can get confusing if children are involved, but this can also become a worthwhile learning experience for them -- knowing how to make their own decisions when things don't sit right.

I would certainly hope that the husband would attend the other church at least once to get a feel for it. I understand what she is going through. The roles were a little reversed in my house. My wife and I decided on a church together. She loved the church and I couldn't barely stay awake. I felt no movement in my spirit on Sunday morning. I had to think outside of the box a little. To worship the Lord is not limited to Sunday morning/evening. I was able to talk her into bible readings together at home in addition to attending her church. We both grew from our Bible readings and she continued to get what she needed Sunday mornings. The very last think I would ever want is to hinder her spiritual growth in any way. With that said, I hope her husband can see that she is in need of spiritual fulfillment.

In any case... 2 hours of church on Sunday morning is less than 2% of our time awake for a week. It's healthy to find ways to grow spiritually outside of church.
