DEMI MOORE at odd with daughters who  try to set her straight about cheating ex-ASHTON again!

RumerScout and Tallulah Willis want their mom, 50, to divorce Ashton now, a year after he was caught cheating on her, so she can finally end that chapter of her life.

 “Demi just can’t let go of Ashton despite him obviously moving on from her, and her daughters don’t think it's healthy or helpful for her,” a source close to the girls told

“They are begging her to get over Ashton and move on with her life!”

After Demi’s trip to rehab her daughters were unhappy with how she continued to deal with her problems, and their relationship rapidly began to fall apart.

They tried to mend fences recently, but according to the source, things are turning sour once again.

“All three girls want her to divorce Ashton and stop talking about him, they think that she needs to focus on the future and quit worrying about what he is doing.

 “Demi refuses to let it go, and her daughters are trying everything they can to get through to her that things are over with Ashton," the source divulged. 

“They love their mom but they want her to stop talking about Ashton!”
