Photographers spotted Spelling and McDermott leaving the hospital on Saturday.
"He would arrive by 10am and didn't leave until 8 most nights. He seemed very stressed out and worried," a source told E!. ''He would bring food and often only left Tori to go outside to catch some air or make a phone call.''
The news comes as Spelling's marriage problems unfolded during last Tuesday's episode of her Lifetime reality series, True Tori. Spelling broke into tears as she described what gossipmongers have known for months -- that McDermott had cheated on her with a woman in Toronto.
"In one moment everything changed," Spelling said of the moment she realized her husband had been unfaithful.
"I can never give him enough sex!" Spelling said through tears on the couple's televised therapy sessions. "He's never gonna be happy with just me."
Spelling told Us Weekly that McDermott "broke my heart," but said she wanted to save her marriage.
