Irreconcilable antipathy arising between the parties to a marriage is not merely a lack of love for one's spouse but an antipathy which cannot be resolved. It is for the Spiritual Assembly to decide whether this condition exists before it sets the date for the beginning of the year of waiting, and this it may do on the application of one of the parties. It is not affected by the other party's not wishing to apply for a divorce.

The date for the beginning of the year of waiting having been fixed, it is the obligation of the parties to make every effort to reconcile their differences and to try to preserve the marriage. The Spiritual Assembly has the obligation to offer them every assistance in this regard ...

Obviously, seeking the assistance of one's Spiritual Assembly is a part of the Bahá'í divorce procedure, and the parties concerned should consult with the Assembly about their problems. It is within the discretion of the parties, or either of them, to also avail themselves of professional marriage counsellors.
