There is no such thing as a perfect relationship, and model Blac Chyna would be the first to say so.

Her relationship with “Keeping Up With the Kardashians” star Rob Kardashian is rocky at best. The two have broken up, reunited and welcomed the arrival of their baby girl Dream.

Chyna said it’s normal for every couple to fight and make up just like them. “I feel like every person who’s in a long-term relationship, or who is committed to their person, goes through ups and downs,” she told Cosmopolitan. “Everything isn’t always going to be peaches and cream. If it is, then it’s fake. I’m in it for the long haul, so I feel like my advice [for anyone in a similar situation] is therapy, know each other’s family, calling each other’s moms.”

Chyna said the important thing is that couples love and respect each other enough to continue the relationship no matter what happens.

“I feel like everything isn’t going to be perfect, but I know we love each other and we’re fighting for each other, and the people we surround ourselves with are rooting for us. It makes everything much easier,” she said.

For now, the biggest issue concerning the couple is the custody of their 5-month-old daughter. According to People, Kardashian has requested for dual custody, but Chyna is giving him some trouble over it.

“Rob wants dual custody of their child and Blac Chyna is giving pushback,” the insider told the magazine. “They are still figuring things out but she will certainly do whatever it takes to have Dream be with her for the majority of the time.”

Despite this fact, Kardashian’s brother-in-law Scott Disick said that the father is hopeful things will turn out for the best, according to the New York Daily News.

“He's my neighbor, we live down the street, so I see him a ton, and he seems to be doing good — new dad, he's excited, he loves his daughter to death, so it can't be that bad,” said Disick.
