Cheryl Cole has jetted off for a holiday with two of her Girls Aloud bandmates, as she agonises over the future of her relationship with cheating husband Ashley.

The pop singer has told friends that she will make her final decision while away in Thailand with Nicola Roberts and Kimberley Walsh.

Cole has been left distraught by claims that Ashley betrayed her by sleeping with glamour model Brooke Healy in 2006 and single mum Aimee Walton in 2007.

"She has been through the most gut-wrenching time and she needed a break," a friend told The Mirror. "She had to get away from the twin influences of Ashley and her family. Ashley has been phoning her constantly but she hasn't been taking his calls.

"Her family are also putting her under pressure of a different kind. They feel that she should just dump him and move on. But the girls in the band have been non-judgmental, which is exactly what Cheryl needs right now. They have all told her they have her unwavering support whatever she decides.

"She still hasn't decided what she is going to do. It's the biggest decision of her life."
