brightcove.createExperiences(); Rob Kardashian is feeling optimistic about the future as he continues his romance with model Blac Chyna.

“Rob has fallen hard for Blac Chyna. She makes him super happy and this is the first time that he’s felt so optimistic about life in years,” a source tells PEOPLE.

The source says that Blac Chyna, 27, has been a positive influence on Kardashian’s health. The reality star, who experienced a recent health scare, has battled depression and weight gain over the past two years.

“She helps keep Rob in check with his health and makes sure he is abiding by his diet and exercising,” says the source. “He feels there’s strong potential for this relationship to go a long way but for now they are very content and complement each other really well.”

Another source says Kardashian, 28, has been “out and about a ton” since starting the new relationship.

“For the first time in forever, Rob seems very excited about the future,” says the source.

Kardashian and Blac Chyna’s romance was made public in late January, with the Keeping up with the Kardashians star, who in recent years has been reclusive, stepping out to support his girlfriend during a steamy beach photo shoot last week.
