Yesterday we all heard the news that Taylor Swift and Calvin Harris decided to call it quits after 15 months of dating. And as per usual, the internet reacted on the fallen Pop-meets-EDM romance.

Not too long ago, Taylor was more than candid in her interview with Vogue about the two, stating: “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.” Amid much heartbreak and fan speculation, we rounded up some of the best theories we could think of as to why the once power couple decided to go thier separate ways.

1.) The infamous Met Gala dance

Taylor and actor Tom Hiddleston hit the dancefloor when the DJ spun T.I’s “Bring Em Out” at this year’s Met Gala. It looked innocent enough, but Calvin didn’t seem like he was feelin’ it. Guess the dance wasn’t so Loki after all.

2.) Calvin Harris’ Car Crash

When Taylor heard the news that her boo was in a car crash, the two had already parted ways, Hollywood Life reports. But the “Blank Space” singer thought the accident could bring them closer. Many reports came in stating that Taylor was nursing his ex back to health, but to no avail. “Calvin kept a lot of things from her on how he was feeling physically because he didn’t want her to cling to him. He appreciated her concern but didn’t want her to care for him.”

3.) He’s Just Not That into (Her)

Perhaps the most simple but painstaking reason the two are no longer together is the fact that Harris simply lost interest. E! News reports that while the two really liked each other, they seemed more comfortable as friends than significant others. “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.”

Both Taylor and Calvin have yet to comment publically on the breakup.. And while many Swifties thought the two would never go out of “Style,” we are certain that Taylor’s heartache will turn into her next huge hit.
