(Yahoo!) - Khloé Kardashian is typically pretty outspoken.

The 29-year-old younger sister of Kim and Kourtney is known as the spunky one, the one who's never afraid to weigh in with her opinion on the family's reality show, "Keeping Up With the Kardashians."

But she's been uncharacteristically quiet about the tough time she must be going through with her husband Lamar Odom, 33. As the NBA free agent has dealt with claims that he's cheated on his wife (Star reported Wednesday that a third woman had come forward), as well as last month's DUI arrest and reports that he's addicted to drugs and recently checked in and out rehab, Khloé has been virtually silent. She's yet to directly take on reports that she hasn't been in contact with her husband and that their marriage is all but over.

The Kardashian Kollection designer has added only one post to her website since August 23 (memorializing 9/11), although she usually posts multiple times a day. (By comparison, Kourtney has made 13 posts this month, and Kim, who's been laying low since giving birth to baby North in June, has made four.)

However, Khloé has sent some cryptic messages through social media that, given the circumstances, could be interpreted as more than they seem at first glance.

For example, last week she changed her profile pic on Twitter from a snap of her with Odom to a shot of just her. On Tuesday, she reposted a quote on Instagram that read, "Sometimes you just gotta be your own hero and save your own little heart. Because sometimes, the people you can't imagine living without, can actually live without you."

Check out some of the other cryptic messages that she's sent during these rocky weeks, in between posts about her show and her family:

While Khloé has been tweeting away, her husband hasn't made a peep since July 12, when he wrote a loving message that was presumably meant for her.

In person, Odom was all smiles when asked about his missus as TMZ cameras caught him leaving Teru Sushi in Studio City, California, Monday night.
