Khloé Kardashian is reportedly disappointed at estranged husband Lamar Odom for going back to his old partying ways.

It has been more than a year since Kardashian filed for divorce from Odom over alleged infidelity and substance abuse.

An insider recently revealed to HollywoodLife that talking to the former NBA player a lot lately gave the "Keeping Up with the Kardashians" star hope for reconciliation.

"For the first time in a long time, Khloé felt like she and Lamar had a real chance at reconciliation," the insider said. "He was really putting his life together. Lamar even told Khloé how much he still loved her."

However, Kardashian is supposedly "heartbroken" yet again, when he ditched his plans to meet up with her and went to Las Vegas to party with his friends instead. 

"He's been partying and hanging out with some people who are bad influences on his life," the insider added. "He once again made partying his priority rather than making things right with Khloé."

Not only that, the athlete is still allegedly struggling with his drug addiction.

Last month, In Touch reported that Odom is on a new drug, following his DUI arrest just 19 months ago.

"He has been doing an old-school drug called sherm, which is taking a joint and dipping it in liquid PCP," a source alleged. "It's really dangerous and can make you violent."

The source also revealed that the reality star is worried about what could really happen to her husband if he continues to take sherm.

"Lamar's friends and family and Khloé are all pushing him to get into rehab," the insider claimed, adding that, so far, Odom has refused to take their advice and continues to party. "Lamar needs serious, serious help."
