The pair are yet to file for divorce and a source tells Radar Online that Demi has been avoiding proceedings because she’s still reeling over the fact that her husband of six years moved on so quickly with his former co-star Mila Kunis.

“Demi has instructed her attorneys to delay negotiations as much as possible," the source says.

“The main issue they have been fighting over has been the division of assets and the monetary settlement, but it's now gotten to the point where Ashton is willing to cave in to all of Demi's demands just to reach a settlement.”

But it seems that despite Ashton agreeing to her terms, Demi is “playing hardball” and continues to throw out new demands.

“It's driving Ashton nuts as he just wants to close that chapter of his life and move on. He and Mila are very serious about each other and although another marriage isn't going to happen immediately, it is definitely something both Ashton and Mila have discussed and believe is in their future,” the source says.

Demi’s tactics aren’t only causing her former husband angst, her behaviour has also sparked another rift with her three daughters, who she only recently reconciled with following months of not talking.

“Rumer, Scout and Tallulah have all remained close to Ashton and they have completely come down on his side," the source says.

"Rumer, especially, is really annoyed at her mother for dragging things out and thinks she is behaving like a total b*tch.”

Demi’s daughters are urging their mother to move on with her life for the sake of her health, but it seems Demi can’t let go.

“As far as the girls and Ashton are concerned, everyone needs to move on with their lives and this whole fiasco has been going on for way too long. However, Demi sees things differently and she cannot forgive Ashton for moving on so quickly to Mila and flaunting their relationship publicly. It's a classic case of a woman scorned."
