Just maybe,

One day we could both switch identities. You'll be me for a day, and I'll be you for a day.

Maybe just then, you'd know it isn't easy to hang on so long? With your hot and cold attitude towards me. With you giving me all the false hopes and leave me hanging halfway..
Maybe, just then you'll know how painful it'll be for me.



But, sorry, I just can't bear to put you in such pain.
