1) Cash takes being Jessica's support system very seriously. "Cashs hand around Jessicas lower body communicates reassurance and support," says Donaldson. And her leaning on him means she's here for it and trusts him unconditionally. Jessica knows that whenever she needs Cash to have her back, he will. Stefanie Keenan - Getty Images
2) They're thriving in the intimacy department. Jessica and Cash aren't shy about showing affection in public, says Donaldson. They do it "no matter whos watching and without reservation" which points to how healthy their emotional intimacy is. Take this photo, for instance. "Jessicas entire body is turned into Cash and she is in his personal space and he does not mind," says Donaldson. It's their way of telling anyone and everyone looking they'll prioritize each other's company over everything else. Gregg DeGuire - Getty Images
3) They're a like-minded couple. You'd be hard-pressed to find something that would come between these two. Donaldson's sure of this because Jessica and Cash's heads touching means they're like-minded and have similar goals for their future. Their leaning on each other means they trust each other fully, plus, it points to the strong bond they have. Jessica Alba / Instagram
4) Their connection runs deep. Even posed, Jessica and Cash are still showcasing what Donaldson calls, "emotional closeness." How? By holding hands. "They chose to be hands on and fully connected palm to palm," she explains. That, along with Cash's other arm around Jessica, are moves that mean they love to share as much space as possible in order to maximize this closeness. Though they might not have intended to, the couple is communicating to anyone looking at this photo that their love is genuine. Cash Warren / Instagram
5) They've always got each other on the brain. "The position of people's feet is very telling of where they want to be or where theyd rather be," Donaldson explains. In this moment, and in most of them for that matter, Jessica and Cash want to be with each other. Even when their attention is on their kids, they still find a way to connect. Not only are they holding hands, but their feet are angled toward each other, meaning they'd prefer to be in each other's arms than anyone else's. Bauer-Griffin - Getty Images
6) They make time for each other no matter what. This deep kiss before Jessica rushes off to the airport, "tells us that they have very intense feelings for each other," says Donaldson. Even when they don't have much time, they'll make some. "We try to just always protect the us time and make time for that," Cash confirmed to Us Weekly . And in this moment, it's no different. Both Cash and Jessica have one foot pointed in another direction because they have other places to be, but the other foot is angled toward their spouse, meaning they're doing their best to make this quick moment a special one.
