“We wouldn’t have got to this moment,” Harry replied. “It’s impossible to say where we would be now — where those relationships would be now — but there is no way that the distance between my brother and I would be the same.”

Colbert then asked Harry about his feelings on being 38, two years older than Princess Diana was when shedied in a Paris car crashon Aug. 31, 1997.

“Well, she died at 36, and I was 36 when this all kicked off,” Harry said, referencing when he and Meghan stepped back from their royal roles. “January of 2020 was when my wife and I basically said, ‘Enough, we can’t cope. We can’t deal with this. We need to carve out something different.’ So that was an interesting overlap of time.”

In this week’sexclusive issue of PEOPLE,Prince Harryopened up about mourning his mother.

“I struggled for years to accept or even speak about my mother’s death. I was unable to process that she was gone. I’m not sure anyone can ever truly have closure when they lose a parent, or anyone for that matter, especially when that grief may be the only thing left of them,“Prince Harrytells PEOPLE of grieving Diana.

“The healing process has allowed me to get to a place where I now feel the presence of my mum more than ever before. She’s with me all the time — my guardian angel.”
