The reality star, who split with longtime girlfriend Kourtney Kardashian in June, shared a photo on Instagram on Friday night that spoke volumes.
Holding a place card that said "Scott Disick Guest" the father of three captioned it, "When you realize the grass isn't always greener."
Presumably the 32-year-old was thinking about all the times that Kardashian was by his side.
Kardashian, 36, dumped Disick after he was photographed cozying up to another woman during a trip to the south of France.

And Disick, who was also spotted kissing a blonde in Vegas last week, isn't the only one pondering his new life.
Kardashian is "taking a hard look a what her new reality could look like," a source told PEOPLE. "Before, she just assumed nothing would really change, but now there's a strong possibility of life without him and that's a scary thought for her. She's figuring it out and taking it as it comes."
