*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, according to TMZ.

Sources close to Humphries’ family say 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.

Not so fast says Kimmy.

TMZ says she’s telling friends … Kris H is full of it when he talks about how much his family loved and supported her.  Kim is saying they had nothing but disdain for her and her family, and never wanted their son to tie the knot.

“It’s ridiculous that Kris’ family is making Kris look like the victim,” says Kim.

She also says the reality is … they constantly “belittled” her, were “nasty” to her family and Kim is saying a lot of this was captured on camera.

On the other hand, Kardashian is telling her friends that her marriage to Humphries was true love, and she’s extremely angry at reports that the wedding was one big sham.

If you care to know, she says the marriage was “100% real,” adding they loved each other very much.

Kim is saying they cultivated their relationship for a year — it wasn’t an overnight thing.  She says when they got engaged … she truly believed the marriage was “forever.”

Well apparently in the Kardashian world, “forever,” is 72 days.

“Sometimes marriages end … rapidly.  Just because it’s short doesn’t mean it’s fake.”
