It's happened to the best of us, Sisters -- and certainly by midlife. Both of us have experienced this unceremonious and cruel "dumping" by people we thought were close, dear friends.

If you have experienced this, you know how confusing and painful it can be. Many women describe the experience as being as painful and heartbreaking as a romantic breakup -- and sometimes worse!

Luckily, we have Liz Pryor on the show to talk about why this happens and what you can do about it when it does. She wrote the amazing book, "What Did I Do Wrong? What to Do When You Don't Know Why the Friendship is Over" -- and we felt so much better after hearing her take. She's talked with thousands of women about this phenomenon -- and, given how common it is, we should all be talking about it more.

Author, speaker, relationship and life advice expert, Liz Pryor, tells inspiring life stories on and off the page. Her first book of advice about female friendship, What Did I Do Wrong? (Simon&Schuster), was a finalist for the Books for a Better Life Award.

Pryor was among 15,000 applicants vying for a position as life advice expert on ABC’s Good Morning America. After a six-month search, on-air competition and public voting process, Pryor was chosen. She spent the next two years on air dispensing advice on all aspects of every day living. 

Pryor later released her provocative, moving memoir, "Look at You Now" (Random House), which promptly became a Chicago Tribune bestseller. The paperback version released in the US and the UK. Look at You Now was most recently optioned for a television series by SONY Television.

Abby and Julie open the episode discussing Abby's big birthday and her newly-embraced theory that sometimes our decisions can only be understood backwards.
