But has Josh now done exactly what she was so afraid of?
The 26-year-old makeup artist hinted in a comment on MAFS Funny that Josh cheated on her.
Commenting on a post about groom Michael Goonan hooking up new intruder bride KC Osborne, one fan commented: "There isn't a man alive that doesn't cheat. I am convinced."
Cathy responded directly to the fan: ""I hear ya sis."
NOOO!
If that isn't confirmation that Josh cheated, we don't know what is!
The comments come after the 29-year-old truck driver refused to confirm or deny whether or not he and Cathy are still together, while chatting to Hit FM's Carly & Seamus.
"I don't know why [other MAFS stars] are doing that. They take the fun out of it," he said. "If someone saw a new movie and told me how it ended, I would be mortified and wouldn't want to see the movie! It takes the fun out of it."
Josh was asked whether or not there would be any legal ramifications for leaking information about the show before it airs, Josh said: "I just signed the contract, I didn't even read it."
We HOPE the comment wasn't about Josh! We aren't sure our hearts can handle it.
