It certainly doesn't feel like it's been seven years since Kate Middleton stepped out of a vintage Rolls Royce at Westminster Abbey in her Sarah Burton for Alexander McQueen wedding dress to marry Prince William and become the Duchess of Cambridge. And yet, here we are! But Will and Kate's epic April 29, 2011 wedding was just the cap to an over-a-decade-long relationship that reads like a fairy tale. Seriously: A small-town girl, born to self-made parents, falls in love with a handsome prince at college and lives happily ever after. It sounds too good to be true, but it's real life, y'all.

From their earliest days as peers at St. Andrews University, where Prince William bid $200 to see Kate walk in a charity fashion show (and now she's the top royal style influencer!), to their recent royal tours, their courtship and marriage has been historic, romantic, and unbelievably adorable—and, fortunately for royal-watchers everywhere, beautifully photographed. And with an ever-expanding family (including their newest little royal, Prince Louis), there's never been more too-cute royal family photos and swoon-worthy moments to fawn over.

Which stand out the strongest? When did Will and Kate make it clear that they would eventually marry? We found the moments in their love story that show why and how they became the picture-perfect family they are today.

In honor of Kate Middleton's 37th birthday on Wednesday, we're looking back at her and Prince William's biggest milestones—and our 41 favorite moments.

Love stories always have a few bumps in the road, and this couple knows that well. After nearly five years together, the two called it quits in April 2007.

But after a few months apart, the royal twosome rekindled their romance, with Kate attending William and Harry's Concert for Diana that July. However, this snapshot of their March 2008 ski trip to Klosters, Switzerland, proved that their relationship was back on track.

December 2006: Kate Attends William's Sandhurst Graduation

Getty Images

William graduated from the Royal Military Academy in Sandhurst, England, more than a year after he and Kate graduated from St. Andrews. That December, he was commissioned as an army officer in front of the Queen and joined the Household Cavalry as a second lieutenant. Kate attended the event and brought her father, Michael; it marked the first time she was a guest of her boyfriend at an official royal engagement with the Queen present. Though now we're more than used to seeing her at royal events, this was a historic moment for the common-born princess.

June 2005: St. Andrews Graduation

Getty Images

Though the story of how Kate Middleton met Prince William is now royal folklore, it bears repeating: The art history majors met while living in St. Salvator's Hall at St. Andrews University in Scotland. As Middleton helped her future husband choose a different major, their romance grew; Prince William famously shelled out $200 to watch Kate walk in a campus charity fashion show. Fast forward four years, and the best friends and roommates posed for this cozy portrait on graduation day. Though they had been dating since roughly 2002, this picture is one of the first public photos of the college sweethearts—they had a privacy agreement with the press during their school years. Following their graduation ceremony, Will and Kate hosted a lunch for Prince Charles, his wife Camilla Parker Bowles, and Middleton's parents. This big moment was the first spark that became the royal couple flame.
