As he's struggled with his recovery, Nick Stahl has disappeared a handful of times for one to four days, but he's always eventually checked in with his wife Rose – and he's always come back, she says.
Then, on May 9, Stahl – who has been living apart from Rose with a roommate – went missing when the roommate took a break from their morning meditation session.

"He could have overdosed, that's one thought. And I'm wondering if there will be a body recovered," Rose tells PEOPLE.
Rose, 30, reported him missing
May 14. Police are not treating the case as a criminal matter and say no foul play is suspected.
His disappearance comes as the pair, who married in 2009, have been coping with a number of domestic problems.
They filed paperwork in early February allowing Rose to keep Nick from seeing their 2-year-old daughter if he fails a drug test, and he had been living away with a male friend since that time.
Still, Rose says she does not consider the two of them separated or estranged.
"That was an adult, loving decision that we made to try to inspire his recovery and maybe even scare him away from relapse," she says.
She adds that Stahl, who at age 13 played opposite Mel Gibson in The Man Without A Face,
has struggled with addiction since his teen years, and the problem has become worse than ever for reasons she doesn't fully understand.
Stahl, who has spoken openly about his problems with drugs and alcohol
, has been turning down parts for the past nine months to focus on his recovery, says Rose. But she adds that his recent disappearance has been difficult on the family, including their daughter.
"She asks for dad. 'Is Dada coming?' And she worships the ground he walks on," says Rose. "But I've had a lot of people coming over, and I've been careful that she not be exposed to too much of my anxiety."
