请问这句英语何解?
I'll be there for you if you should need me you don't have to change a thing love you just the way you are.

这个句话原自一首歌曲!中英文对照如下:仅供参考!
If I had to live my life without you near me
The days would all be empty
The nights would seem so long
With you I see forever
Oh,so clearly I might have been in love before
But it never felt this strong
Our dreams are young and we both know
They'll take us where we want to go
Hold me now
Touch me now
I don't want to live without you
(CHORUS) Nothing's gonna change my love for you
You ought to know by now how much I love you
One thing you can be sure of
I'll never ask for more than your love
Nothing's gonna change my love for you
You ought to know by now how much I love you
If the road ahead is not so easy
Our love will lead the way for us
Like a guiding star
I'll be there for you if you should need me
You don't have to change a thing
I love you just the way you are
So come with me and share the view
I'll help you see forever too
Hold me now
Touch me now
I don't want to live without you
(CHORUS) Nothing's gonna change my love for you
You ought to know by now how much I love you
One thing you can be sure of
I'll never ask for more than your love
Nothing's gonna change my love for you
You ought to know by now how much I love you
像是一个无法解开的谜题
你给我的爱
如此的神奇
像是一出无法结束的电影
剧中的主角
全部都是你
还要多少的勇气
去面对未知的风雨
我的心和你的心
总在做着同样的决定
你就是我爱情的原因
当你说出那一句 i love you
你就是我唯一的梦
梦中不再有任何分离
你就是我爱情的原因
为你说出那一句 i love you
我已是你唯一的梦
我们的爱此情永不移
像是一个无法解开的谜题
