"Taylor felt he wanted to take the relationship to be too public," a source close to the situation tells us, "and she was not happy about it and thought it was too much publicity."
The couple, who made headlines after photos of them kissing on a beach in Rhode Island went public in June, dated for about three months. Taylor and Tom became official after the 2016 Met Gala, where they were spotted dancing the night away. After getting together, they traveled the world together. Tom flew to Nashville to meet T.Swift's parents and friends, and then the "Style" songstress made her way to the U.K. where she spent time with Tom's parents. From there the very public couple flew to Rome, where they packed on the PDA at Coliseum and enjoyed romantic dinner dates in Italy. But because Tom had to film Thor: Ragnarok, the couple traveled to Australia where Taylor visited a local children's hospital and Tom worked.
Tom also attended Taylor's annual Fourth of July party, where he hung out with many of her A-list friends (and wore an I Heart T.S. shirt while doing so).

Because of the swiftness (pun intended) of their relationship, some wondered whether their relationship was for the headlines. But Tom denied those rumors to The Hollywood Reporter. "Well, um," he answered, apparently with a laugh. "How best to put this? How best to put this? That notion is—look, the truth is that Taylor Swift and I are together, and we're very happy. Thanks for asking. That's the truth. It's not a publicity stunt."
In fact, a source told E! News that Taylor and Tom fell head over heels for each other. "Taylor and Tom are in love with each other. He told her she is the kind of woman he wants to spend his life with," an insider told us. "They have gotten very close. She is enjoying the time off from working. She has been writing during her travels, and Tom has been an inspiration in her music."
But as quickly as their relationship heated up, it started to die down. The "Out of the Woods" singer and The Night Manager actor were seen less and less and public, save for a dinner date here and there. Perhaps all they wanted was a little more privacy in their relationship, or maybe it was a warning sign.
Us Weekly was the first to report the breakup.
