Suing an ex for heartbreak, and taking a leap into sobriety

Break-ups in the modern era don't leave us with much recompense, except for maybe "forgetting" to return an ex's favourite book, but what if you could take legal action and charge your ex with ‘lacerating your emotions’? We look back at the Breach of Promise Act, a moment in history when Australians lived could sue former lovers for emotional damages, and what it says about how we love today. Plus, in the fourth instalment of Leap, we meet Derick Cusack, who leapt from substance abuse into marathon running and never looked back.
