Like her previous relationships, Taylor Swift's last relationship did not last also. Taylor and boyfriend, Calvin Harris have allegedly broken up. Although many are surprised by the split, there are also many others who were not surprised anymore.

News that Taylor and Calvin have broken up was not something that comes as expected in recent days, based on observations by people on the two. Allegedly, the two seemed to be getting serious and more in love as days went by prior to them breaking up, as reported in Eonline.com.

An insider shared to E! News the events that occurred prior to Calvin (Adam Wiles in real life) and Taylor breaking up:

"He liked how innocent Taylor was and that she had a good caring heart. Taylor's heart was more in it than he was. He started to lose interest over the past few months, but really tried to not just break up."

The insider shared that Taylor and Calvin were just not a match in their relationship. The source said the pair was like more friends than being boyfriend and girlfriend. One of the strains in the relationship was the constant travelling and touring of the pair.

The source was quick to add, though, that both parties did not cheat on each other at all. The insider shared as well that Taylor was in Nashville with her family, who has been standing by her all the way to be of help to her after she's broken up with Harris.

The insider said Taylor was disappointed Harris was not there for here whenever she needed him. The source also added Taylor does not intend to get back with Harris.

Taylor and Harris allegedly talked about plans of getting married just the previous month, as reported in The Mirror UK. 

Taylor and Harris have been romantically involved for 15 months as of the time they have separated, as reported in USA Today.
