Scott Disick reportedly feels he is being used for ratings by partner Kourtney Kardashian and her mother Kris Jenner.
The Keeping Up With The Kardashian stars have been dating since 2007, and are already parents to son Mason and daughter Penelope.
Disick has been appearing regularly on Kardashian's reality television programs, Keeping up with the Kardashians, and Kourtney and Khloe Take Miami.
"He's fed up with being used like a guinea pig to boost ratings, and bitterly blames Kourtney and her mom for making him look like a loser and a fool," a source told OK! Magazine.
Adding on, the insider said that "the biggest source of tension between him and Kourtney, because of course she's driven by money and publicity just like her mom."
"He drinks too much and hasn't been perfect but he's had a horrific year with the deaths in his family and would dearly like to take a break from the spotlight," the source added.
It was previously reported that the 35-year-old reality TV star is worried that Disick could leave her before the birth of their third child.
Disick expressed shock and anger when Kardashian revealed she was pregnant for the third time.
Meanwhile, Kardashian had recently revealed the gender of their unborn child on Kourtney and Khloé Take The Hamptons.
"I am so happy we're having a boy. It's going to be perfect for our family," she said.
