Your forever telling me I'm weak
When I'm critized I never speak
I prefer to turn the other cheek
But I will love you all my life
I can never do things right by you
I'm the kind of man who muddles thru
You can find mistakes in all I do
But I will love you all my life [ Lyrics from: http://www.lyricsmode.com/lyrics/c/charlie_landsborough/i_will_love_you_all_my_life.html ]
Something foolish happens and you see
In the Middle of it all there's me
Seems I cause you so much misery
But I will love you all my life
All my life, All I own
Everything is yours alone
Everyday my whole life thru
I will spend loving you
Everybody says for you I'm wrong
You'll get nowhere Fast with me along
They keep telling me I don't belong
But I will love you all my life
All my life, All I own
Everything is yours alone
Everyday my whole life thru
I will spend loving you
Basically, it's all to do with another song (when a man loves a woman) - he loves this woman, despite all her knock backs and regardless of the end result, she will always be the 'one'
