Pietro, come to Berlin [...]. I can not live without you. You have to kidnap me from here [...]. I would rather eat dry bread than live longer with that fat oaf". King Frederick was initially unwilling to agree to a divorce, as his sympathy was greater for Elisabeth Christine than for Frederick William, but the Crown Prince insisted in his demand for a divorce, and urged in agreement with the King the annulment of his marriage on grounds to avoid claims of illegitimate offspring on the Prussian throne, to which the Brunswick court agreed.
