everything I do I do it for you

This morning when driving, I heard this song again from the radio. Even listened thousands of time before, listening now sounds so much different. It is not appreciation for the music any more, but become a big sige deep in the heart. some sadness and some touching feeling. just know it could be so hard to find a person who could do everything for you. It is just your own romatic thinking and expect for that.
Anyway, to memorize all the good feeling for this song, still want to put lyrics here:

Look into my eyes
You will see, what you mean to me
Search your heart, search your soul
When you find me then, you'll search no more

Dont tell me its not worth trying for
You cant tell me its not worth dying for
You know its true, everything I do, I do it for you

Look into your heart, you will find
There is nothing there to hide
Take me as I am, take my life
I would give it all, I would sacrifice

Dont tell me its not worth fighting for
I cant help it, theres nothing i want more
You know its true, everything I do, I do it for you

There is no love, like your love
And no other, could give me more love
Theres nowhere, unless you're there
All the time, all the way

You cant tell me its not worth trying for
Just cant help it, theres nothing in the world i want more
I would fight for you, yeah I'd lie for you
Walk the wire for you, yeah I'd die for you

You know its true
Everything I do, I do it for you
