We're right there with you, wondering how Taylor Swift moved on from what appeared to be her strongest relationship yet...But as the saying goes, not everything is as it seems.

Sources tell E! News the singer and Calvin Harris (real name Adam Wiles) had been "checked out" of their relationship for a while leading up to their eventual split.

"Their rhythm as a couple was just off," the insider explains. "They beated to a different beat. Taylor and Adam have been checked out for sometime now."

One of the biggest problems they struggled with was Taylor seeking attention Calvin didn't have the time to give her.

"Distance was a big issue," a second source notes. "Taylor was touring for a lot of the time and Calvin has his appearances all over the world, too, so the long distance aspect caused a lot of distress. There were other things, but the distance was one of the main things that Taylor especially struggled with."

Their distance and the fact that they had been checked out made it easier for both of them to move on and move forward. Taylor is now reportedly dating Tom Hiddleston, with whom she was spotted kissing on Wednesday.

"Adam is over Taylor in every way shape and form," our first source explains. "He knew she was talking to someone towards the end of their relationship."

However, another insider promises there was absolutely no cheating that occurred while Taylor was still with Calvin.

In fact, Taylor and Tom aren't anything serious just yet. "Taylor is hanging out with Tom. Nothing serious is going on but she is talking to him," another source told us. "They have been out a few times she really enjoys his company. She is not looking to jump into anything this fast, but will take things as it goes nice and slowly."
