When Sarah Catherall's marriage fell apart, it felt like a car crash. Grief, uncertainty and shame swallowed her whole. Shared friendships and extended family connections dissolved: it was a break-up of her entire world.

What she wishes she could tell herself now is that the worst thing that could ever happen to her became undeniably the best thing. Fifteen years on from her separation and stronger and happier than she has ever been, this is Sarah's guide to breaking up well, so that you can rise from the ashes as powerful and authentic as you can be.

With stories of her own, from dating 'sad dads' to holidaying as a solo parent with kids, Sarah shares her mistakes so you don't have to make the same ones. She gathers wisdom from relationship psychologists, sociologists, lawyers and divorce coaches; and advice from many others who've been through messy break-ups on such things as 'bird-nesting' adjustments, co-parenting well, and when to introduce new partners to your kids.

How to Break Up Well teaches you how to grow in strength by: finding your support network, regaining your confidence, practising self-care and identifying what you want and need from singledom. You will also read about how to leave a difficult relationship, the most effective ways of fighting for your kids and your assets, how to blend families with a new partner, and how to learn from your break-up so you can charge into the next chapter of your life fully healed.
