if this song is about you dont listen to it

I don't think you realize What I would do for you And I don't think you know The things I did for you I'd sacrifice the end of time I'd do anything to make you mine For the rest of my life For the rest of my life, alright I just wanna know what it's like To be by your side Just one more time And I never meant to make you cry But now I see your tears drop from your eyes You're in my nightmares every night And I just wanna make you mine But now you're long gone and I see That there's no more left of you and me
