"Kourtney often complains Scott doesn't help her, but she doesn't really want him around the kids," a source told In Touch magazine.
"She's trying to divide her time between work, Mason and Penelope, and it's overwhelming."
Scott, 29, has been flying across the countries for parties without his family and even left Kourtney and the kids to head to New York City for Fashion Week.
"He thought nothing of leaving Kourtney and the kids behind and flying to New York. It's sad but typical," the source told the tabloid.
"He lied to everyone and said he was just coming to NYC to host a Fashion Week event, but that was far from the truth. He was hanging out with his guy friends and hit up Soho House. He tried to keep his whereabouts off the radar so he wouldn't be photographed or piss off Kourtney."
Not only did Scott take off across the country, but In Touch claims he partied with tables of other women.
"They're just random girls who he's met through his various trips to NYC; it happens all the time," the insider said.
"Sometimes he calls in from L.A. to comp women's meals."
