Los Angeles-born Meghan has plenty of friends in California, but Harry "doesn't have friends" - or a job.
"So at the moment he's a bit rudderless," the source said, adding that Harry knows "it won't always be like this".
As part of his agreement with the Queen, Harry no longer uses his official military appointments, as the couple also gave up their HRH titles and their Sussex Royal Instagram account on March 31.
Despite the fact that it's a quiet month for Harry, the couple have shared some details of their new life with the world.
Meghan returned to acting this year, narrating Disney's Elephant. The couple also announced a new charity in April named for their son Archie, called Archewell.
