Taylor Swift and boyfriend of 15 months Calvin Harris,32 have gone their separate ways. While fans may be mourning the end of the relationship at least they will have a new break-up song to look forward to!

News of the split has shocked many as it seemed Calvin Harris (real name Adam Wiles) and Taylor, 26 were really getting along and things looked to be getting more serious as the months went by.

Sources say that the relationship had just run it’s course and there  was no shady business involved.

“Adam 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. Taylor’s heart was more in it then he was. He started to lose interest over the past few months, but really tried to not just break up,” the source said.

“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 added. “Taylor and Adam had very different group of friends,” the source noted, and reassured that Harris “100 percent did not cheat. There were no other women involved with Adam. He did not cheat on her at all. Just not a good match.”

Taylor has gone back to Nashville to be with her family following the break up. The source continues to say, “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.”

Neither of the stars have spoken out about the breakup.

Let’s just hope Taylor puts all those feelings onto paper and pens herself another mega-hit break up song!
