Not the one for you

He didn't mean to hurt you.
But darling he isn't the one for you,
and no matter what you do,
know that he's crying too.
Because you where the best he had.
And now he'll realise it's too sad.
That he left you the way he did,
and for everything he said,
know that he'll never be the same.
And one day he'll wake up in pain,
for he'll remember everything the two of you,
use to mean to both of you.
And that day he wakes up to her.
He can only think of you,
he'll lose his speech, slur
and call her you.
And then she'll know it's all over for her too.
