Taylor Swift & Calvin Harris Breakup 'Wasn't a Shock' to Her

It seems there were several reasons behind Taylor Swift‘s split from Calvin Harris.

The 26-year-old “Blank Space” singer and 32-year-old DJ recently broke up after 15 months together.

“[Calvin] said on multiple occasions that he was intimidated by Taylor, which is why he would not attend any events where she was being honored, or any award shows unless he was nominated,” a friend of Taylor‘s told People. “Taylor is an independent young woman, and she realizes it will take a very secure man to handle her success.”

A source close to Calvin told the mag that the split “wasn’t a shock” to Tay and the relationship wasn’t “leading anywhere.”

“They come from very different worlds,” the source said. “Taylor is used to being treated a certain way.”

The person also said, “It wasn’t an equal relationship. Their age difference might not be significant for many couples, but for them it was part of the problem too. Taylor somewhat lacks real-life experience. They will not be getting back together.”

“She works incredibly hard for things that she believes in,” Calvin‘s source said. “He always saw that as an amazing quality. They are still friendly.”
