'Cause I'm not your princess, this ain't our fairytale
I'm gonna find someone someday, who might actually treat me well
This is a big world, that was a small town
There in my rear view mirror disappearing now
And it's too late for you and your white horse
Now it's too late for you and your white horse
To catch me now
No, Ed is a fan of John Mayer. They are both talented singer-songwriters. These things are what attracted Taylor to both of them because that is something she relates to and admires. OK, her relationship with John ended sourly, but that is no reason for Ed not to still like John Mayer or his music.
Taylor is friends with Gwyneth Paltrow, but she is still paying compliments to Chris Martin, even though their marriage broke up. Taylor still seems friendly with Niall Horan, despite her falling out with Harry. Similarly Cara Delevingne and Ed Sheeran are friendly with both Taylor and Harry Styles.

Taylor doesn't need those high school dramas in her life. Her friends can be friends with whomever they want and if Taylor can accept that, I don't know why some of her fans can't.
