While many reports have claimed that Rob’s increasingly reclusive behavior, weight gain, and alleged drug use were spurred on by the negative behaviors of former BFF and roommate Lamar Odom, but it seems as though it was the loss of Lamar as a family member that truly sent Rob on a downward spiral.
A source close to the family reveals to TMZ that the constant fighting between Khloe Kardashian and Lamar, which prompted him to move out of the couple’s home, started him down the bad path he’s on today.
The source claims that it was Lamar’s rejection of the entire Kardashian family, and not his drug use, which Rob was never privy to, that sent Rob into a tailspin.
The insider adds that Lamar was the first male role model Rob connected with since the devastating death of his father and hero, Robert Kardashian Sr., in 2003.
Although Khloe is quick to defend her brother, his disappearing act seems to be increasingly alienating other members of his family, who have made his troubles a major plot point on recent episodes of KUWTK.
