"It can sometimes seem a mystery why some couples stay together and thrive--while many more split up or drag on scratchily. Fortunately, though we might ascribe happy love to chance, there are a range of identifiable secrets that underpin all good relationships and that we can learn and put into practice. With decades of experience behind it, in a tone that's warm, encouraging and often funny, this book teaches us the key ingredients of contented love: how to air grievances, the best way to share a home and--when things grow truly problematic--how to judge whether or not we should stay or leave. This book shows us how to take the necessary, careful, intelligent steps towards the contented love we deserve"--Back cover.
