EXCLUSIVE: Kevin Costner's estranged wife Christine Baumgartner wants actor to 'lighten up' and end 'childish silent treatment' now that she's moved out of their $145million home

Kevin Costner's estranged wife Christine Baumgartner is hoping her relocation to her new home will alleviate tensions between the couple and put an end to the actor's 'silent treatment', sources reveal.

Earlier this week, DailyMail.com published photos of the Santa Barbara rental home Baumgartner, 49, is moving into after she was ordered to vacate the $145million Carpinteria, California compound she had shared with the 68-year-old Yellowstone star in their divorce. 

Now, a close friend of the designer has said that the move has come as a relief for Baumgartner whose initially amicable split from her estranged husband turned sour  and left her in an uncomfortable living situation. 

'Christine said she feels like the weight of the world has finally been lifted now that's she's moved out,' the insider told DailyMail.com.

Baumgartner, 49, found a new home in Santa Barbara, California after she was ordered to move out of their marital home 

'She said she wouldn't be surprised if Kevin had the staff keeping tabs on her while she was packing up.

'She still doesn't understand why Kevin had to drag her name through the mud and make what could have been rather easy, painfully difficult.'

The source revealed that Costner and Baumgartner have had no verbal contact 'in months' and have only been communicating through their lawyers - much to her dismay. 

'Christine hopes that will one day end so they can establish some sort of amicable relationship for the sake of the kids,' the insider added. 

'She said the silent treatment is ineffective and childish and that Kevin needs to lighten up, especially now that he has the house.'

Following her July 28 move from the main home, an insider revealed to People that the mother-of-three had been staying 'at a smaller house' on the property that had been used for staffers. 

The insider said that Baumgartner had been 'staying in the area to not disrupt' her her and Costner's three children - Cayden 16, Hayes, 14, and Grace, 13 - who 'will be back at school in the fall with their friends' in the coming months.

Baumgartner, a handbag designer, has been 'trying to keep everything as normal as possible' amid the tumultuous time for the family, the source told the outlet. 

Baumgartner, who filed for divorce from the Yellowstone star in May, has complained of struggling to find an appropriate rental abode in the area.

Since proceedings began, the divorce has been far from amicable, from Costner claiming that his ex refused to leave the mansion despite giving her $1.45 million for a new residence; to Christine alleging the actor was trying to make her and their children 'homeless.'

Baumgartner had insisted in court docs that she had no plans to 'strip' their mansion in Santa Barbara of items before leaving the grounds.

Costner - who was spotted with the pair's three kids July 28 in Aspen, Colorado -  and Baumgartner have been locked in a very contentious split over the past few months.

Last month, sources told DailyMail.com that Baumgartner fears the performer is 'out for revenge' against her after she filed for divorce, and will have police escort her out of their Santa Barbara home.

'He wants to humiliate her,' a close friend of Christine said. 'This isn't about the house, it's about making Christine's life a living hell for actually going through with the divorce.

'Christine said she wouldn't be surprised if Kevin had her escorted off the property by police,' the friend says. 'It was Christine who wanted to make this transition as peaceful as possible for the sake of the children.

'Kevin has done the complete opposite. He's not thinking about the kids, about how traumatizing this is.'

Last month, a judge also ruled she must confer with Kevin before taking any property from the estate. She has been barred from taking art, furniture, furnishings or appliances with her, without his explicit consent. 

The former couple initially tied the knot in 2004, with Christine filing for divorce on May 1 after 18 years of marriage.
