Taylor Swift opened up about her relationship with ex-boyfriend One Direction famed singer Harry Styles without taking his name. The “Bad Blood” hit maker said that she felt anxious throughout her relationship with Styles. Swift admitted that she never really felt like their romance would last because they were constantly facing obstacles.

Swift and Styles split in early 2013 after just three months of dating. “The number one feeling I felt in the whole relationship was anxiety. Because it felt very fragile, it felt very tentative,” the 25-year-old singer said. Popularly called Tay, the singer added that their relationship always felt like “what would be the next road block?”

Swift, who is from Nashville, said that she used to be in perpetual fear about what would happen to the relationship? She would always keep thinking how long it would last like a month or three days before they would break up.

But Swift, who is now dating Scottish DJ Calvin Harris, insisted that their short-lived relationship, which also inspired several other tracks on her most recent album “1989,” still meant a lot to her and was perfect in its own way in spite of all the drama.

She performed an acoustic version of her track “Out of the Woods” which is believed to be about her British ex-boyfriend. In a new video released by the Grammy Museum to celebrate the record’s one year anniversary, Swift opened up about the relationship that inspired her album.

The “We Are Never Ever Getting Back Together” hit maker introduced the song and said that a lot of relationships can be very solid which is what everyone hopes for, a solid and healthy relationship. But, the pop star added that always it does not happen.

The “Out of the Woods” number has been co-written with Bleachers’ Jack Antonoff. Swift has been spent almost the whole of 2014 touring after the release of "1989." She will finally wrap up her world tour on Halloween, Saturday, in Tampa, Florida.
