It has been said that David told his wife Courteney Cox that she must choose between him and Jennifer Aniston… Somehow I doubt this is true but the story goes like this:

“According to reports, the actor is fed up with having to share his wife with her best friend, and has told friends that he feels like he is married to two women.
Since splitting up with Brad Pitt, Jennifer has been inseparable from Courteney, and has spent nearly every public holiday with the couple, and even joined them on a recent holiday to Hawaii.

"Somewhat understandably, David's now saying it's him or Jennifer. He's had enough and is drawing a line in the sand," said the mystery source. "He's asking that Jennifer's visits become less frequent and that there are no phone calls between midnight and 8am."

Good like with that David.
