Remember in her Vogue interview when Taylor Swift said, “There’s just been this earth-shattering, not recent, but absolute crash-and-burn heartbreak”? Now we know who may have been the one to crush our girl. Who’s the guilty party?

Reports point at none other than actor Jake Gyllenhaal. A friend told Us Weekly, “She’s haunted by that relationship. He totally screwed with her mind.” Ouch! The pair did have a large age gap (Gyllenhaal is 31), so that likely didn’t make their relationship an easy one. Combine that with their hectic schedules and the pressures of paparazzi following their every move and it’s not surprising that it wouldn’t last.

Considering the breakup was a while ago and their relationship only lasted about three months, why is it so hard for Swift to move on? The pal dished, “She doesn’t know how to meet anybody new.”

While that may seen far fetched considering Swift is one of the most famous girls on the planet right now, also keep in mind that Hollywood is actually a pretty small dating pool, and it can be tough to weed out non-celebs who actually like her from those who like the idea of her. “If someone doesn’t seem to want to get to know me as a person but instead seems to have kind of bought into the whole idea of me and he approves of my Wikipedia page? And falls in love based on zero hours spent with me? That’s maybe something to be aware of,” she told Vogue. “That will fade fast. You can’t be in love with a Google search.”

So do we have another potential ‘Dear John’ track on our hands? It appears that way. “The songs on her next album are intimate and revealing,” another pal spilled. “Some are about Jake.”
