Long before they announced their split and introduced the world to the term "conscious uncoupling,", Gwyneth Paltrow and Chris Martin were struggling to stay a couple.
In this week's cover story, several friends tell PEOPLE that the pair, who were married for 10 years, at times had an "open" relationship.
"They were physically separated and emotionally," says a Paltrow insider.
Adds a close friend of the 41-year-old actress: "They have been on and off for many years. The marriage was falling apart."
