Even so, why'd the flame burn out so quickly? Before we answer that, let's first take a stroll down memory lane…
Oct. 23: Their first public outing as a couple appears to have been an afternoon of apple-picking at Fishkell Farms in Hopewell Junction, N.Y. Later that night, they attend broadcast of Saturday Night Live in NYC.
Oct. 25: Reports hit the internet claiming that the two are more than just new friends after they're spotted together in Brooklyn brunching with another couple at restaurant Al Di La.
Nov. 13: Gwyneth Paltrow hosts a dinner party for Gyllenhaal and Swift at her and Chris Martin's London home, according to US Weekly. Paltrow later tells USA Today, "I've just known Jake for a long time and he's a great guy, and Chris has a friendship with Taylor."
Nov. 25, Thanksgiving Day: It's another Brooklyn sighting when they're photographed on a date at Gorilla Coffee (they had a couple of lattes). Swift is also snapped by paparazzi strolling through the neighborhood with Gyllenhaal's sister Maggie and little niece Ramona.
Nov. 27: They leave New York for Swift's hometown of Nashville, where they stop by Fido, a coffeehouse not far from Music Row. The next day, it's cappuccinos at the city's Frothy Monkey. They continue their tour of coffee houses the next day with a stop at Crema. Less than 24 hours later, they were back at the Frothy Monkey.
Dec. 8: Swift reportedly returns to Los Angeles to hang out with her beau at his Hollywood Hills home. The next day, they're spotted zooming around town in Gyllenhaal's Audi.
Dec. 13: Gyllenhaal is not by Swift's side as she celebrates her 21st birthday at her family's home in Hendersonville, Tenn.
Dec. 19: Brokeback Mountain actor turns 30! He told reporters about a month before that he planned on marking the milestone with a family vacation in the—ready for this?—Arctic Circle. No word if the trip actually happened.
Jan. 4: Sources confirm that the two are dunzo. Our own Awful Truth reports that both are "very happy" it's over.
Jan. 5: So what happened? Sources confirm Gyllenhaal initiated the breakup because he didn't like the media attention and he also felt their nine-year age difference was a problem, too. But no time for sad faces—it's announced that Swift's Speak Now will remain at the top of the Billboard 200 chart next week.
