'RHOBH' Kim and Kyle Richards Epic Feud: Brandi Glanville's Bestie Not Returning Sister's Text Message Following Kid's Hospitalization for Depression

It doesn't seem like the feud between Kim Richards and her sister Kyle Richards is going to get better anytime soon. The RHOBH stars are reportedly still at each other's throats following a tumultuous last couple months. After Kyle's daughter got bit by Kim's pitbull Kingsley and issues revolving around Kim's sobriety, it seems that their relationship has taken a turn for the worst. Now it seems that Kim isn't even responding to Kyle's text messages anymore. According to Radar Online, one of Kim's children -- Kimberly, Chad, Whitney and Brooke -- who she shares with her exes Monty Brinson and Gregg Davis, has checked into a mental illness facility for depression. But it seems that Kim isn't looking for any support from Kyle, as she hasn't even responded to her messages.

"Kyle has texted Kim to check in regarding the hospitalization, but she hasn't received any response," the insider explained. "The sisters are further apart than ever even though Kim could use Kyle's support. It's just an incredibly sad situation because Kim has so much stress in her life including dealing with her beloved ex-husband Monty's terminal cancer."

It seems Kyle is being the bigger person in the situation and has agreed to stop her feud with Kim during this rough time, but Kim isn't having it, according to The Inquistr.

"Kyle is frustrated with Kim because she was willing to put their issues on hold, and to be ignored was just a slap in the face," the source explained.

The good news in this situation is that Kim's child is doing well and will remain in the hospital for the next few weeks as they are being observed.

"Kim's offspring is expected to remain in treatment and a patient at the hospital for the next two weeks," the reports claimed. "She has been visiting on a very routine basis, and is just heartbroken about the situation, but doesn't want to discuss it with Kyle."
