Since then, he has continued to honor his ex’s life, in bothtributes on social mediaand speaking out during interviews.

In the May issue ofEssence, Combs revealed he’s beena lot more involved with his familybecause he knows that’s something Porter would want.

“Before this, I was a part-time father, you know? My family was always first, but there are countless times when I chose work over everything else,” he explained. “But every day I can hear her telling me to go and spend some time with the kids and make sure everybody’s all right, like she would do. I’m just a lot more present, and, most important, now my kids come before anything else in my life.”

Though their grief will never go away, Combs said the family is doing “really well.”

“We have a great family … the way we’re handling it together,” he said. “We’re doing really because her passing has changed us and made us love each other more. I’m happy to say that, because at first I really didn’t know how we’d be doing.”

“Because of Kim, we’re doing this well, because of the way she loved us,” he added.
