Welcome to dumpsville, population you

It's just not working out
It's not what I expected
It's not you, it's me
I'm setting you fee
You'd look better with somebody else
I'm really sorry
I don't get on with your friends
(I'm nothing to savour)
It's the same problem we had last week
(I'm doing you a favour)
I miss every call for boy's night out
You're lucky I'm leaving
You deserve better
