Tori and Dean have been together since 2006 and share five children: Liam, 15; Stella, 14; Hattie, 10; Finn, nine; and Beau, five. McDermott also shares 23-year-old son Jack with ex-wife Mary Jo Eustace.

The actress’ friends are worried as they won’t hear from her again, according to the source. Friends have tried to reach Tori but never received a reply.

“She stopped doing social things. She seems to be isolating. She was so upset that if she has money problems again or is depressed, they worry that something will happen,” the source said.

The insider also claimed Tori and her friends didn’t get together like they used to.

It was also claimed by another source that the couple put the divorce on hold due to their “roller coaster” relationship.

The source claimed the couple feels “trapped” as they are unable to go through with the divorce.

“They know divorce is going to be expensive, and they’re not ready to go through that right now. They both feel trapped,” the insider told the site.

“Having kids makes it harder because they don’t want their kids to be unhappy, but at the same time, Tori has been unhappy for quite a while. They really are still together for their children.’

Both Tori and Dean attended daughter Stella’s middle school graduation on Wednesday. The duo posted lavish tributes to their daughter on Instagram.

Dean and Tori have been at the center of divorce rumors for the past year, when a source close to Spelling tells E! News that she was reportedly preparing to file for divorce from her husband.

The insider claimed there was no going back for the couple, but that the 90210 star wanted to make sure she was “financially stable” before filing the divorce papers.

“The marriage is over and has been for a very long time,” the source said, adding that the couple “really don’t get along” and “have been sleeping in different rooms for months.”

Tori added fuel to the fire when she appeared on SiriusXM’s Jeff Lewis Live, where she confirmed the couple sleep in separate beds.

‘What’s really going on? You put on the wedding ring. Are things okay?’ Lewis asked her after she was spotted without her ring in March. “Because I have a feeling the last time you were here everything was fine, you had sex. Do you guys sleep in the same bed? Personally?’

‘You know what? Right now my kids and dogs are sleeping in my bed,” she replied, continuing that McDermott slept “in one room.”

It is claimed that a major cause of disputes between the couple is trust issues stemming from Dean’s infidelity, which he admitted on reality show True Tori in 2014.

A source told People: “Tori still has major trust issues. Part of their relationship was never fully repaired after he was unfaithful.

The insider revealed the couple’s outings together are just for the sake of their kids.

“They led separate lives. You’ll still have family dinners and the occasional outing, but it’s for the kids.
