Kris Humphries' Family: Kim Is Making a Massive Mistake

Kris Humphries' family has been crushed by Kim Kardashian's decision to end their marriage -- telling friends, the reality star is making a massive "mistake" for giving up on Kris so soon.

Sources close to Kris' family tell TMZ, everyone knew there was tension in the relationship -- but they never imagined divorce was on the table. As one source put it, "Everyone fights."

The Humphries believe Kim is making a huge "mistake" -- insisting she never gave the marriage a fighting chance ... and should have tried harder to make things work.

That said, Kris' fam still believes he can salvage his marriage and talk Kim down off the ledge, convincing her to slam the brakes on divorce proceedings.
