The problem with love is that it is unquantifiable. Thus, nobody can really say that a man loves a woman more than she loves him. But that fact is not stopping some royal family fans from speculating on whether Prince Harry or Meghan Markle is more in love than the other.

Some people believe that Prince Harry loves Meghan more than the duchess loves her husband. However, this observation is rather unreliable as it is based on what is referred to as the “look of love,” an indicator that is subject to individual interpretation.

“Well, what I will say is that Harry gives Meghan the ‘I love you look’ a lot more than she does to him,” actress Tiffany Smith claimed. Smith will portray Meghan in an upcoming film titled “Harry & Meghan: Becoming Royal.”

To Smith’s credit, she has been studying the Duchess of Sussex, as well as Prince Harry, for around a year before she gave her verdict. The actress has been observing how the two royals gaze at each other on TV, so she gets her portrayal of Meghan on the film just right. Of course the fact that the duchess is a former Hollywood A-lister actress is probably putting some pressure on Smith as well.

Surprisingly, it’s highly likely that Smith might have been influenced by her grandmother on how she views couple dynamics. “I remember my grandmother would always tell me: ‘You need to make sure that the guy loves you more,’” the actress added. “But I don’t know if that’s necessarily what I’d want.”

Smith also revealed a few hints on what the upcoming movie could bring. It would deal with how Meghan tried to blend in with the royal family but ended up feeling pushed around too much that she had to finally make a stand.

As a mom, Meghan’s biggest motivation to make her stance clear is her family. “In the first film you see a moment where Meghan retreats into herself, in this one there’s a feeling of her saying: ‘Look — we are married now, and I’m not going anywhere, which is why I’m making a stand,” the actress added. “‘So if you’re going to try and push my buttons, then I’m going to push right back.’ I certainly don’t see Meghan as subservient in any way.”

Meanwhile, there are also people who believe that both Meghan and Harry love each other equally. “Meghan clasps Harry’s hand throughout the interview, it’s like she doesn't want to lose touch with him for a second,” commented Darren Stanton, a body language expert, after seeing the couple interviewed by BBC’s Mishal.

Although Meghan is very confident of herself, Stanton noted that she would often look at Harry after answering a question, as if seeking confirmation that he is happy. “Overall, it’s clear they are very much in love and have mutual and utter respect for each other,” the body language expert concluded.
