After just seven months of dating, Prince Harry and Meghan Markle are secretly engaged — but distance is putting a damper on their relationship.

Sources reveal exclusively to Life & Style that the British royal is miserable when the Suits actress leaves England, and was in a days-long funk after he dropped her off at London's Heathrow airport right before the holidays.

Harry, 32, and Meghan, 35, were in high spirits when she spent a week in London, picking out a Christmas tree and seeing a play together, with Harry calling it "one of the happiest weeks of his life."

The couple, who reportedly met in Toronto during the Invictus Games, is not wasting any time and Life & Style previously reported they are ready to start a family in 2017.

"They’ve discussed having babies together, and they both can’t wait," says a source. “Many of his friends have kids, and Harry is at that phase where he feels ready, especially now that he’s found the woman of his dreams.”

However, Queen Elizabeth II is not too thrilled with her grandson's choice of girlfriend, telling her inner circle she does not "fit in" and it would be better if Harry dated a socialite who comes from money like his previous girlfriends Chelsy Davy and Cressida Bonas.

"Her Majesty is mortified that Harry's in a relationship with a divorcée who does steamy scenes on TV," an insider says, referring to Meghan's previous marriage to film producer Trevor Engelson.

In the meantime, Harry is working to bridge the 3,500-mile gap between them.

"He's planning on whisking her away very soon to an exotic location," says the insider, "so they can have a holiday in the sun."
