Scott's partying had been an issue in their relationship for quite some time and that seemed to be the last straw, as the photos appeared during what was reportedly a month-long bender where he had not returned home to see his family.
After the breakup, Scott canceled two scheduled club appearances and then did an appearance at 1OAK in Las Vegas, where he appeared much more subdued than usual.
While being single and free to mingle after nine years might have sounded appealing to Scott, it sounds like he's now realizing it isn't everything it's cracked up to be - and that what he had with Kourtney was pretty special.
The reality star attended a wedding last night and shared this photo of a seating card with the caption, "When u realize the grass isn't always greener."
A lot of fans were quick to point out that he should have realized that sooner, but still others were telling him it's not too late. "Go get your Beautiful Girl and wonderful family back," one person wrote.
"Amen! Now fix your mess," another chimed in.
Of course, Kourtney would have to be open to reconciliation, which doesn't really sound like a possibility ATM, but you never know!
