In answer to a comment above, the congregation has no place in trying to solve marital disputes. I remember as an Elder being taught that we should never give advice or tell people what to do. “ Would you like to be responsible if it goes wrong?” They should just point out the scriptural principals.
Another situation for a woman is if her husband leaves the faith.. She becomes a “ spiritual widow “. My wife has said how the various congregations have treated her totally different to when she was an elders wife.
