Taylor Swift never talked publically about her relationship with John Mayer though many thought she spoke out about it through her music with the song "Dear John" from her album Speak Now.  Though she never confirmed it, John Mayer thinks it's about him, too, and he's not happy about it.

In the new issue of Rolling Stone, John says the song "made me feel terrible, because I didn't deserve it." He adds, "I'm pretty good at taking accountability now, and I never did anything to deserve that. It was a really lousy thing for her to do."

John says what he really bothered him is that he learned how Taylor really felt about him in the song, and not from her directly. "I never got an email. I never got a phone call," he says. "I was really caught off-guard, and it really humiliated me at a time when I'd already been dressed down. I mean, how would you feel if, at the lowest you've ever been, someone kicked you even lower?"

When Rolling Stone asks about the song's key line, "Don't you think I was too young to be messed with?," John replies, "I don't want to go into that."

Not only does he object to song because it's about him, but John also tells Rolling Stone that as a songwriter, he feels it's not right to use your skills as a weapon. "I think it's kind of cheap songwriting," he tells the magazine. "I know she's the biggest thing in the world, and I'm not trying to sink anybody's ship, but I think it's abusing your talent to rub your hands together and go, 'Wait till he gets a load of this!' That's bullsh*t."

Here are the lyrics...

Long were the nights when my days once revolved around you
Counting my footsteps praying the floor won't fall through again
And my mother accused me of losing my mind
But I swore I was fine

You paint me a blue sky and go back and turn it to rain
And I lived in your chess game, but you changed the rules everyday
Wondering which version of you I might get on the phone tonight
Well, I stopped picking up and this song is to let you know why

Dear John, I see it all now that you're gone
Don't think I was too young to be messed with?
The girl in the dress cried the whole way home
I should've known

Well, maybe it's just me and my blind optimism to blame
Or maybe it's you and your sick need to give love then take it away
And you'll add my name to your long list of traitors who don't understand
And I'll look back and regret how I ignored when they said run as fast as you can

Dear John, I see it all now that you're gone
Don't you think I was too young to be messed with?
The girl in the dress cried the whole way home

Dear John, I see it all now it was wrong
Don't you think nineteen's too young to be played with?
Your dark twisted games when I loved you so
I should've known

You are an expert at sorry and keeping lines blurry
Never impressed by me acing your tests
All the girls that you've run dry have tired, lifeless eyes
'Cause you've burn them out

But I took your matches before fire could catch me
So don't look now
I'm shining like fireworks over
Your sad, empty town

Dear John, I see it all now that you're gone
Don't you think I was too young to be messed with?
The girl in the dress cried the whole way home

Dear John, I see it all now it was wrong
Don't you think nineteen's too young to be played with?
The girl in the dress wrote you a song
You should've known

You should've known
Don't you think I was too young?
You should've known
