Taylor seemingly opened up about their romance on her album The Tortured Poets Department, which was released in April.
Through her songs, Taylor suggests that she and Matty enjoyed a nine-year on-again, off-again situationship of sorts, which was rekindled towards the end of her six-year relationship with Joe Alwyn.
Taylor appears to reveal that she fantasized about Matty while still with Joe, and as soon as she ended things with the latter, she phoned Matty to start things up with him.
The star also sings about being love-bombed as she seemingly accuses Matty of preying on her vulnerabilities by promising her marriage and children and hinting at proposing to her after she was left unhappy with the fact that Joe never did.
However, after just a few weeks of officially dating, Taylor suggests that Matty abruptly ghosted her, leaving her absolutely devastated.
She started dating NFL star Travis Kelce the following month, and Matty moved on with Gabbriette two months after that.
