The answer to today's most pressing question Love is one of the most powerful forces in our lives. It's the reason we open our hearts to someone we hardly know, marry them and tie our destinies and bank balances together. Love is also what prompts us to start a family. However, if that love is challenged or dies, it can also be the force that propels us apart - prompting us to consider leaving our partner, breaking our children's hearts and sometimes moving half way across the world to be with someone new. If love makes our relationships thrive and the lack of it makes them wither and die, we better have a good idea what we mean. No wonder 'what is love?' is the most Googled question and something that has pre-occupied and divided poets, philosophers and psychologists for hundreds of years. Marital therapist Andrew G. Marshall has spent 30 years helping couples struggling to understand and cope with the fall out from love, and in What is Love? he's gathered together 50 of today's most pressing dilemmas to shed new light and help you find a way forward, including... Why can't I find love? Have I fallen for the wrong person? Why did the spark go out and the passion drain from our of sex life? Should I stay in a OK marriage or look for something better? Why has my partner fallen out of love? Can you love two people at the same time? How do you rebuild love after an affair? When is it time to accept the inevitable and move on?
