Impossible Lyrics
Someone told me I should take
Caution when it comes to love
I did
My illusion, my mistake
I was careless, I forgot
I did
There is nothing to say
You have gone and so effortlessly
You have won
You can go ahead tell them
Shout it from the roof tops
Write it on the sky line
All we had is gone now
And my heart is broken
All my scars are open
Tell them what I hoped would be
Impossible, impossible
Impossible, impossible
Falling for betrayal is worst
Broken trust and broken hearts
I know, I know
Building faith on love and words
Empty promises will wear
I know, I know
There is nothing to say
On your own you can go ahead tell them
Shout it from the roof tops
Write it on the sky line
All we had is gone now
And my heart is broken
All my scars are open
Tell them what I hoped would be
Impossible, impossible
Impossible, impossible
Someone told me I should take
Caution when it comes to love
I did
Shout it from the roof tops
Write it on the sky line
All we had is gone now
And my heart is broken
All I hoped would be
Impossible, impossible
Impossible, impossible
Impossible, impossible
Impossible, impossible
Impossible, impossible
Impossible, impossible

I think he is saying that people warned him about love & the dangers of it & he thought he listened to them but when he actually got his heart broken he now realises what they were talking about & it was more terrible than he ever imagined. So he is basically saying "Tell them they were right about love" This is my interpretation & experience, probably interlinked.

I Interpretate This Song To Be Him Being Wrong About What He Thought Love Was . He Is Saying That Thought Love Couldn't Be This Painful .He Is Embrassed ('And if you're done with embarrassing me') Because He Thought He Knew Exactly What He Was Getting Into('Someone told me I should take Caution when it comes to love I did') But In The End Love Was Just What He Wish It Wasn't Going To Be .('Tell them what I hoped would be Impossible') And That He Is Not Ashamed Of His Mistake . ('Tell them all I know now Shout it from the roof tops Write it on the sky line All we had is gone now ') But The Pain And Hurt Is Still There .('Tell them I was happy And my heart is broken All my scars are open')

this song match with my life, because he got many warning from he's environment but he still do it. he overconfident about he's love story. finally, he falling out, and regret. "falling for betrayal is worse" <---- this lyric exact with my love story.
