London: Singer Taylor Swift says she doesn`t understand how to make her relationships last.
The 22-year-old, who is currently dating One Direction hunk Harry Styles and has previously romanced Conor Kennedy, Taylor Lautner, Jake Gyllenhaal and John Mayer, laments the fact that none of her romances have worked out but she is hoping her luck might change in the future.
"I don`t understand how to make relationships last. I`ve never had a really long relationship, so I have no idea what that`s like. Wish me luck for the future," femalefirst.co.uk quoted Swift as saying.
