Here's my shot at what would be helpful: "The Sacrament of Matrimony is intended to be a perpetual union. Spouses should make every effort to avail themselves of the grace of Christ to live by their vows to one another and to God. If, however, in consultation with the Church, they discover valid reasons to separate, they may do so without breaking communion with the Church and its sacraments. Those currently in non-sacramental marriages should approach the Church to seek reconciliation with the same confidence, and pastors should consider it their duty to reconcile the spouses with Christ and the Church."

That would be a start.
