There were multiple theories as to why Taylor Swift and Calvin Harris called it quits, but according to a source close to the “All Too Well” singer, the root cause of the split was Harris being “intimidated” by her success.”[Harris] 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,” they explained to People. “Taylor is an independent young woman, and she realizes it will take a very secure man to handle her success.”
Meanwhile, another insider told E! Newsthey split simply because they weren’t compatible. They were polar opposites and came from different circles — and there’s the fact that they also had busy schedules. “They were just not very compatible in different areas in their relationship. The touring and traveling didn’t help. It seemed like they were more friends than lovers,” the insider claimed. “Taylor and [Harris] had very different group[s] of friends.”
But another source assured fans that they split amicably. “Taylor and [Harris] had no big blowout fight, but the romance just was not there anymore for them,” they divulged. “Adam is the one that ended it. It was all done in a very mature fashion. Taylor is pretty upset but they are still in communication. Taylor was there for Adam with his accident and supportive.”
