The 22-year-old is currently dating Conor Kennedy.
"I still believe in love, even after love explodes into a million pieces and burns down and you're standing in a pile of the ash of what it once was thinking, 'Why did I have to meet this person, why did this have to happen?'," showbizspy.com quoted her as saying.
"But then, when you make eye contact with someone across the room and it clicks and, bam, you're there. In love again," she added.
Asked if she falls for people she likes easily, Swift said: "Not if it's the wrong person, yes if it's the right person.
"Well, it's not like it's in fine print. But music is absolutely everything that I am and everything that I stand for. It's not my fault if someone gets into a relationship with me and then cheats and I write a song about it," she said.
