Josh Flagg breaks down on tonight's Million Dollar Listing: Los Angeles.

'MDL' Couple Josh Altman & Heather Bilyeu Set New Wedding Date

While visiting the former home of his late grandmother, Edith Flagg, who had often been seen on the show, Josh has an emotional moment as he goes through her belongings.

"It's only been nine months. It doesn't feel like it... I honestly just feel like she's on vacation," Josh explains in the sneak peek. "She would go to Paris by herself and just walk around and go and have seven or eight cups of coffee and sit at the piano... and just talk to the piano player and listen to him as he played songs that she liked. It's surreal that she's not here."

"Since she's left, I haven't heard from her, but maybe I just don't know how to listen," he continues, as another scene shows him going through old photos of Edith.

And while the reality star and successful realtor planned on moving into the Los Angeles penthouse with his partner, he is now having second thoughts about doing so.

"I thought what I wanted was for me and Colt to move in here, but it's harder than I thought. It's not the same without her here," he explains.
