FriendDean Cain, who competed with Todd on NBC’s 2012 reality seriesStars Earn Stripes, had dinner at their Wasilla, Alaska, home a few months agoand told PEOPLE they seemed fine.
“They seemed wonderful together,” Cain said. “I’d hate to speculate on the cause — what happens behind closed doors, and how people grow and change over time is something no one can ever predict or understand, save those two people.”

“I know that they’re both extremely devoted and wonderful parents,” Cain continued, “and I’m certain that they’ll both remain dedicated to Trig and their other children.”
A listed attorney for Todd didn’t immediately respond to PEOPLE’s request for comment on Monday; neither did he nor Sarah.
