Speaking on a podcast, Meghan said the couple struggled to fully enjoy one another's company early in their relationship as they were quickly put into "the trenches" by the media spotlight.
The pair started dating in 2016 and married in 2018, initially taking on royal duties before deciding to step back from their roles in 2020, leading to strained relations between Harry and the King and the Prince of Wales.
In an appearance on a podcast from entrepreneur Jamie Kern Lima, the co-founder of IT Cosmetics, Meghan said she has been able to better appreciate her relationship with the Duke of Sussex since stepping back.
"You have to imagine at the beginning, everyone has, like, butterflies," she said.
"Then we immediately went into the trenches together. Yeah, right out of the gate, like six months into dating.
"So now, seven years later, when you have a little bit of breathing space, you can just enjoy each other in a new way, and that's why I feel like it's more of a honeymoon period for us now."
The duchess praised her husband for keeping the family "safe".
Harry settled his long-running legal battle with News Group Newspapers in January, receiving substantial damages and a "full and unequivocal apology" for "serious intrusion" into his private life and "unlawful activities" by The Sun.
Harry is also involved in a legal battle with the Home Office over the level of taxpayer-funded personal security he should receive when visiting the UK.
"He's just out there, just constant, like he's just going to do whatever he can to make sure that our family is safe and protected and we're uplifted and still make time for date nights," Meghan said.
"He's also a fox. If you haven't noticed, my husband's very, very handsome. But his heart is even more beautiful."
Meghan became emotional when talking about her children, Archie and Lilibet, and revealed that she sends emails to secret addresses she has created for them to read when they are older.
"Before I go to bed, almost every night, I email them, like, here's your report card from today, or, oh my gosh, wasn't it the funniest thing this morning?
"Or here's a picture of you two having breakfast, or here's you playing.
"The things that you're not going to frame, the things that you're not going to put pen to paper in a journal, but which they will end up seeing at one point in their life, maybe when they're 16 or when they're 18."
