No wonder Kim Karadshian pulled the plug on her 72 day marriage. If Karadshian insiders are to be believed, Kris Humphries truly turned into Mr. Hyde after the couple’s dream wedding on Aug. 20.

The NBA star especially seemed to channel his resentment over the NBA  season lockout,seeming to get seriously resentful of workaholic Kim after she kept up her non-stop working ways, while he partied with his friends.

“He tried to control Kim by bringing her down,” a source tells Us magazine. “He would say truly terrible things. One time, he said she had no talent and her fame wouldn’t last.”

From there it went from bad to worse. Here’s what Kardashian insiders say he did to turn Kim from a loving wife into sad woman determined to get a divorce.

“He belittled her in front of people,” an insider says Us magazine. “He’d call her stupid. It was truly sickening.”

“Kris was so different,” after the wedding, insists a friend of Kim’s. When the star first met Kris, “he was fun and low-key and Kim thought, that is it.”

But Kris got nasty to Kim once they were back from the honeymoon. He called her “fat ass,” says an insider. And when Kim wanted to spend time with him, “he would tell her she was acting like too much of a wife and ‘get over it.”

Kris would spend almost every night out partying while Kim was at home or working. “He started to love the life, going out every night partying,” says Kim’s friend. “He and his friends had never experienced anything like that and started to demand free tables, free bottles ( at clubs). It was embarrassing to her. She goes to bed at 9 p.m.”

“When he drinks with his friends, he gets wild,” continues the Kardashian insider. And when he went to Miami without Kim in October,  he “was definitely not on good behavior.”

Kris loved being hit on at Liv nightclub in Miami, claims a source from the club. “The girls were bragging about dancing up on Kim’s man.”

“He was definitely scoping out other girls,” another source, who met Kris at a Hollywood club, claims. “If someone brought up Kim, he would laugh and say, ‘Oh, yeah, everyone loves me now because of Kim.’”

Now, Kim is heartbroken and living in misery. “She’s distraught and has been in bed a lot,” a source reveals. “Her sisters have been over. She wants to go on vacation and decompress.”

“She’s trying to figure her life out,” agrees the Kardashian insider.

“Kim wanted the relationship to work so bad,” says another pal. “It was hard to see her like this.”
