Taylor Swift and Calvin Harris Split

It's over between Taylor Swift and Calvin Harris, sources have confirmed to "Extra."

An insider told People, "There was no drama. Things just don't work out sometimes.”

Rumors are swirling that Calvin, real name Adam Wiles, was the one who put the brakes on the relationship. A source revealed to E! News, "[Calvin] really liked Taylor, she was not the type of girl he ever dates and he liked that. He liked how innocent Taylor was and that she had a good caring heart... 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 source also shut down rumors Calvin was unfaithful, saying, "There were no other women involved with Adam. He did not cheat on her at all. Just not a good match."

Another insider revealed when Taylor and Calvin went their separate ways. "This all happened last week. Taylor and Adam had no big blowout fight, but the romance just was not there anymore for them. 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."

As for how Taylor is dealing with the split, a close pal commented, "She was in Nashville with her family and they have been helping her through the breakup. Taylor was really disappointed in Calvin and felt like he wasn't there for her. The relationship wasn't progressing the way she wanted it to. She felt like he wasn't taking it seriously enough and wouldn't come through for her when she needed him most. She felt down and like her needs weren't being met. She doesn't want to get back together."

One childhood friend Taylor may be leaning on is Abigail Anderson, who posted a tribute after the split. She posted a note card with the words, "My weird heart loves your weird heart."

Just two weeks before news of the split broke, Taylor and Calvin were spotted sharing a hug and kiss at the airport after their Caribbean vacation in photos obtained by Daily Mail.

Taylor opened up about Calvin to Vogue in April, revealing, "I'm just taking things as they come. I'm in a magical relationship right now. And of course I want it to be ours, and low-key... this is the one thing that's been mine about my personal life.”
