She's dated Joe Jonas, John Mayer, Taylor Lautner, Glee's Cory Monteith and now Jake Gyllenhaal, but Taylor Swift admits she has some romantic neuroses.
"It's a little strange that I'm typically single a lot," the "Mine" singer, 20, tells the December issue of Allure.
"I have a phobia about being in the wrong relationship," admits Swift. "So as soon as I establish it's not the right one, I don't want to waste their time."
Even if she hasn't found Mr. Right just yet, the country superstar -- who recently spent three cozy weekends in a row with Gyllenhaal, 29 -- admits she's addicted to love.
"Relationships are fascinating and riveting and completely unpredictable," she gushes. "For me, love is everything."
Swift has, at least, evolved from the high-school approach to relationships, and tells Allure she once gave bad relationship advice to pals.
"I used to think there were all these rules for making people like you," Swift chuckled. "I was filled with advice! I'd tell my friends things like, 'Don't accept that apology! That isn't sincere!' or 'He hung out with his ex-girlfriend? Get rid of him.' But love is never that simple."
What about her famous penchant for writing her exes into thinly-veiled songs?
"I can only write the material I know, which is what happens to me," says the singer, whose Speak Now was met with blockbuster sales and critical acclaim. "And luckily I've had a crazy two years. Not just careerwise, but emotionally, too."
