What did i do wrong

The cold days are slowly fading away
so it's getting warmer day by day
We broke up almost year ago
why you have left me I still don't know

I thought we shared so many things
realized you only are a minx
I explained you my philosophy
then you tell me that you don't agree

(Chorus):
So what did I do wrong
why do I sing this song
tell me what did I do wrong at that time
now I can't find another rhyme

The only thing I do now is wasting my time
do nothing else sitting at home and drinking wine
Must not think so much, think so much of you
but what else am I supposed to do
