Before he met his now-wife, Meghan Markle, Prince Harry's longest relationship was his on-again, off-again romance with Chelsy Davy, which started in 2004 and ended in 2010. After their split, the exes have remained on good terms and Davy reportedly accompanied Harry as his plus-one to Prince William and Kate Middleton's royal wedding in 2011, the year after their breakup.
In the years since they ended things for good, both Harry and Davy have made it clear that royal life and the scrutiny that comes with being (or just dating) a member of the royal family was the primary reason for the split. Ultimately, Davy realized that it wasn't the life she wanted for herself, and if royal life wasn't right for her, then continuing a relationship with a prince just wasn't possible.
