The 22-year-old, who is currently romancing One Direction singer Harry Styles, previously dated Conor Kennedy, Taylor Lautner, Jake Gyllenhaal and John Mayer but none of her relationships lasted long.
Swift hopes her luck might change in the future, reported Daily Mail.
"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," she said.
