What's the Name of That Book??? discussion

This was an American non fiction book published within the last 20 years or so. I think it was early 2000s but I could be wrong. It had a red and purple cover with two overlapping circles on the front.

I think the book had 2 authors who were academics/sociologist types. They had interviewed lots of people who had either been dumped or dumped their partner. In the book there were excerpts from the anonymised interview transcripts, which were organised by theme, e.g. the first chapter was about "moments when people realised things were starting to go wrong" all the way through to the aftermath of the breakup.

A common theme was that one partner usually gets dissatisfied first and does not immediately tell the other person, so it is often a shock when they actually confront their partner.

I'd like to recommend it to a friend but can't remember the author/s or title - any help appreciated.
