"I couldn't handle it, I left," Disick, 32, says of visiting Odom at the hospital. "I didn't know what to do."

During Odom's recovery, Khloe Kardashian withdrew her pending divorce from the troubled former reality star.

However, since that time, Kardashian refiled for divorce on May 26, citing irreconcilable differences. The two are reportedly on good terms and Odom was aware the second filing was coming.
