The Duke and Duchess of Sussex stepped down as senior members of the Royal Family last year. Meghan and Harry relocated to the US with their baby son Archie.
Tom Brady, ITN news anchor, said he thinks Prince Harry is heartbroken by the situation with his family.
But he added the couple are “content” with their new situation and excited about their projects.
Mr Brady was a guest at the Sussexes’ wedding in 2018 and he has previously interviewed the couple before they decided to step down from royal life.
During an interview on Love Your Weekend With Alan Titchmarsh, due to be broadcast today, Mr Brady spoke about Meghan and Harry.
He said: “I think they are content, the things they are doing they are quite excited by.
“I think Harry is heartbroken.
“You don’t necessarily need to have the knowledge to know that, but I think it is true.”
Mr Brady added: “The situation with the family clearly isn’t ideal. It’s been a difficult year.”
He said: “It is painful all-round, painful for everyone, difficult to manage.
“Effectively they have just decided to completely leave the Royal Family, that has never been done.”
In an interview with Mr Brady for the documentary ‘Harry & Meghan: An African Journey’, filmed before the Sussexes stepped down, the Duchess explained how she was warned by her British friends.
Meghan said: “I had no idea, which probably sounds difficult to understand here.
“When I first met my now-husband, my friends were really happy because I was so happy, but my British friends said to me, ‘I’m sure he’s great, but you shouldn’t do it because the British tabloids will destroy your life.”
Since moving to the US, Meghan and Harry have signed deals with the streaming giants Netflix and Spotify.
Royal commentators are anticipating the Sussexes’ return to the UK.
Phil Dampier, author of Royally Suited: Harry and Meghan In Their Own Words, claimed the Sussexes’ and Cambridges’ first reunion will be “awkward”.
He told the Sun: “I think it’s going to be very awkward if they do meet up.
“From what I am told the rift is not a lot better at the moment – they are not talking a lot.
“I think they will put on a united front for the unveiling of Diana’s statue and I’m sure they will put on a united front for the birthday celebrations but behind the scenes I think there’s going to be a lot of tension.”
