The meaning of John legend (All of me) for me

What would I do without your smart mouth
Drawing me in, and you kicking me out
Got my head spinning, no kidding, I can’t pin you down
What’s going on in that beautiful mind
I’m on your magical mystery ride
And I’m so dizzy, don’t know what hit me, but I’ll be alright

My head’s under water
But I’m breathing fine
You’re crazy and I’m out of my mind

'Cause all of me
Loves all of you
Love your curves and all your edges
All your perfect imperfections
Give your all to me
I’ll give my all to you
You’re my end and my beginning
Even when I lose I’m winning
'Cause I give you all of me
And you give me all of you oh

How many times do I have to tell you
Even when you’re crying you’re beautiful too
The world is beating you down, I’m around through every move
You’re my downfall, you’re my muse
My worst distraction, my rhythm and blues
I can’t stop singing, it’s ringing, in my head for you

My head’s under water
But I’m breathing fine
You’re crazy and I’m out of my mind

'Cause all of me
Loves all of you
Love your curves and all your edges
All your perfect imperfections
Give your all to me
I’ll give my all to you
You’re my end and my beginning
Even when I lose I’m winning
'Cause I give you all of me
And you give me all of you
Give me all of you oh

Cards on the table, we’re both showing hearts
Risking it all, though it’s hard

'Cause all of me
Loves all of you
Love your curves and all your edges
All your perfect imperfections
Give your all to me
I’ll give my all to you
You’re my end and my beginning
Even when I lose I’m winning
'Cause I give you all of me
And you give me all of you

I give you all, all of me
And you give me all of you oh

Well, John Legend used this song when he proposed to his fiance, so I think it's pretty safe to say this song is about loving someone fiercely and endlessly, and asking them to share in a relationship of trust but the other side  I also think it's about unrequited love. About being in love with a person no matter what, even though you don't really want to. Being in love with a person, who doesn't love you back. And how much it hurts
inside...

You’re my downfall, you’re my muse
My worst distraction, my rhythm and blues
I can’t stop singing, it’s ringing, in my head for you

 (my fave part of this song, :P)
