Couples in the early stages of a relationship have countless guides to choose from. But what about those who have been together for a while or for a really long time? A long relationship always gives rise to questions – regardless of whether the partners are in their thirties, forties or fifties. Around two thirds of all couples are uncertain about their relationship, and question – either openly or secretly – whether they want to carry on like this. Dr Werner Bartens says that those who give up on a long-standing relationship are giving up on a treasure trove of shared experiences and trust that the couple has built up over the years. Research has shown that those who are in a relationship are healthier and happier and, in contrast to what singles might think, have a lot more sex. But a long relationship is also demanding - Werner Bartens explains what matters in a proper relationship, regardless of age. It doesn’t matter if you don’t have butterflies in your tummy – in fact, it’s better, says Bartens, because you will feel as happy in your long relationship as you felt at the beginning of it. Relationship guides almost always address couples who have recently got together. But what about the many couples who look at their relationships after years and find themselves dissatisfied? Finally, a relationship book for couples who have been together for a while. You ask yourself: is this just the way it is, or can I change things? Can I revitalise our partnership? Doctor and publicist Werner Bartens has written a book that really helps people in this situation.
