The 26-year-old flew out to Los Angeles last week to get some space from the footballer, who is still the subject of further tabloid revelations about his love life.
While Cole was yesterday snapped on a 'date' with US Strictly Come Dancing star Derek Hough, she has since told friends that she is weighing up whether to move on from her cheating spouse.
According to the Sunday Mirror, she told a friend: "I can’t forgive him this time."
The insider - who has been close to the star for several years - revealed: "She is very upset and said she is going through hell at the moment. Her emotions are all over the place and she has been veering between bouts of crying and anger as she tries to work out what to do.
"She is very confused and, in one of her low points, she said to me, 'I can’t forgive him this time'. She’s gone from sticking by him to now being furious and asking how he can keep humiliating her like he is.
"When Ashley strayed before, she believed there was something to salvage," the source continued. "But now she's not so sure. She's furious that his indiscretions are mounting up and making her look like a fool. She feels people are starting to think she’s an idiot by staying quiet and not saying she's leaving him, and she doesn't want this to affect her career.
"She's determined to return from LA with her mind clear and made up."
