The Good American co-founder, 39, appears on the cover of the latest issue of tmrw, opening up in the accompanying interview about her dynamic with ex Tristan Thompson, with whom she shares son Tatum, 17 months, and daughter True, 5½.

“With me and Tristan, would it be really easy to never talk to him again and to just badmouth him or whatever? Of course. But it’s way harder to be nice,” Kardashian says of the co-parenting relationship.

“It’s way harder when you’re really mad at someone, it’s really hard to sit in their face in front of your kids and be like, ‘Hi!’ ” she says.

“Trust me, that’s not how I feel every day,” she candidly shares. “I had to learn to take control of my feelings. There were so many times that my feelings got control of me and I was impulsive and I tweeted something or posted something and things that you regret. But in my opinion, I’ll never regret being a nice person.”

By keeping things amicably with the 32-year-old NBA star for her kids, Kardashian believes she’s “protecting their innocence.”

“I want my kids to have beautiful relationships with their dad. And if we’re blessed enough to have a dad that wants to be there and wants to show up and be hands-on, why would I prevent that from happening?” she adds.Elsewhere in the interview, the mom of two talks about how her preschooler doesn’t have a cell phone, making her an outlier among her peers.

“Some parents allow their kids to have cellphones or this or that. And I’m like, there’s no chance in hell would my daughter have a cell phone right now,” she says.

“There’s no need. You’re 5 and a half. I just don’t understand who they’re calling!” she laughs. “I don’t see her getting a phone or anything like that until she’s 13.”

Kardashian’s own relationship with social media and the ugly side of it influences her feelings about True entering that world.

“I just don’t think comments and that many people having access to you or having an opinion about you is healthy at my age. And I’m 39, so I can’t imagine the impact that has on someone mentally and emotionally in their young, formative years,” she reasons.

“I’ve read the craziest articles about all of that, or people in Congress saying how suicide rates go up. It’s scary. And I’m completely aware of all that and I want to protect my children. Who wouldn’t?”
