Ashton hasn’t looked back since Demi announced their split in October but insiders tell us that Demi is ‘beyond devastated’ that Ashton has been ‘ignoring’ her!

Demi Moore is nursing a broken heart but she isn’t getting any sympathy from her estranged husband Ashton Kutcher. Demi’s publicist announced on Jan. 24 that Demi checked into rehab due to the “stresses in her life” and Ashton doesn’t seem to care.

Demi’s 23-year-old daughter Rumer Willis  called Ashton and asked him to help her but he ignored her call!

“Rumer is devastated,” a source tells us. “She worries day and night about her mother and has been watching her mom fall apart. Rumer actually reached out to Ashton on several occasions and he just blew her off. He either wouldn’t answer or he’d say he’d help but nothing would happen. Bruce [Willis] is a big help right now.”

We told you that Demi spent Christmas at the Parrot Cay Resort in Turks and Caicos and that an eyewitness watched Demi “dance like crazy” and “embarrass” Rumer.

“Because of the stresses in her life right now, Demi has chosen to seek professional assistance to treat her exhaustion and improve her overall health,” a statement from Demi’s publicist reads. “She looks forward to getting well and is grateful for the support of her family and friends.”

Meanwhile, Ashton has been focusing on his starring role on Two and a Half Men and recently tweeted pictures of himself partying in Sao Paulo, Brazil.

“Without Demi, Ashton would not have gotten the Two and Half Men gig,” another source says. “Demi feels almost used by Ashton and like a fool. She feels ignored and can’t believe this happened.”
