Peregrin uncertainty

I have been thinking, thinking about, where I would've gone wrong with you
I struggled to find answers and I didn't know what to do
Now I see you kissing this other man, he makes you happy and that's okay
But I'm worried that if this will end, you'll come crying someday
And I know you don't care about me, but I care about you
You don't seem to realise that I don't have to know you that well
I know I might not be someone with who you could be comfortable
But I'll stay by your side
It's hard to find someone, to rely on these days
But I'll try to comfort you, with a cliché phrase
I'm gonna stay true to you if you stay true to yourself
Take time to think
And I know you don't care about me, but I care about you
You don't seem to realise that I don't have to know you that well
I know I might not be someone with who you could be comfortable
But I'll stay by your side
Life is like a puzzle, love is the last piece
No one could possibly find love, until the puzzle is complete
You have to have lived life to the fullest to see
That early love leads to uncertainty
And I know you don't care about me, but I care about you
You don't seem to realise that I don't have to know you that well
I know I might not be someone with who you could be comfortable
But I'll stay by your side
