"I can't see her reaching out to me, especially now ... or Harry for that matter, but I think both of them are turning into lost souls at this point", he said.
He went on to confirm that the resolution he and the Duchess sought was to continue to serve the Queen "without public funding". "Sadly that wasn't possible", the prince, the sixth in line to the throne, said.
"When I lost my mum 23 years ago, you took me under your wing", he said, referring to Princess Diana, who died in August 1997 after a vehicle she was in crashed while being pursued by members of the paparazzi.
Prince Harry was pictured having a laugh with Lewis Capaldi after his first speech at a charity event about stepping back from the royal family. Through their roles as President and Vice President of The Queen's Commonwealth Trust, The Duke and Duchess have worked to support a growing network of young change-makers across the Commonwealth and will continue to do so, especially in the run up to CHOGM 2020.
"We are taking a leap of faith - thank you for giving me the courage to take this next step", he said.
He continued: "I was born into this life, and it is a great honour to serve my country and the Queen".
"I've accepted this, knowing that it doesn't change who I am or how committed I am", he said.
Susanna Reid has slammed her Good Morning Britain co-star Piers Morgan after he hit out at "pathetic" Prince Harry's "whining".Losing her cool on Monday, 20 January, Reid hit back at Morgan, asking: "Why do you have you keep having a go at him?"
For the first time after the development, Prince Harry spoke about the "great sadness" that followed after his wife Meghan Markle and he made a decision to give up their royal titles as part of a separation agreement with the Queen.
The royal couple can no longer use their royal titles, and they will no longer be receiving funding from the royal family.
The Queen said the agreement was a "constructive and supportive" way forward for her grandson and his family.
Harry reportedly isn't the only member of the royal family who's down about the whole thing, though.
While everyone was shocked to hear their decision of stepping away from their royal life, as it turns out, it's something that's been in talks for months due to all the challenges they have been facing since getting married.
The Prince said he upheld the utmost respect for his grandmother, his "commander-in-chief".
Harry had agreed to attend today's summit before the Sussexes "stepped back" from royal duties 11 days ago.
The couple intend to repay 2.4 million pounds of United Kingdom taxpayer money for the refurbishment of Frogmore Cottage, which will remain their United Kingdom family home as they split their time between Britain and Canada.
Markle and her husband Prince Harry sparked a global media frenzy earlier this month with their decision not to continue as senior members of the British Royal Family.
Prince Harry and Meghan Markle chose to leave the Royal family and now, the younger of the two princes is also opening up about the reason why! "I was sure that the Royal family, which has been around a very long time, will find a way forward", Mr Johnson told Sky News.
