Renaming you for the purpose of these lines would be appropriate

I will call you Judas…

…fitting, is it not?

No, you don't see it

You don't see anything anymore; giving me the task

of recounting the tale of your new name

And now I stand at a crossroad

Do I start with the beginning; the good times,

or in the present day; the silence that is now?

Days of friendship, gone

Left with nothing but silence

and a realization: I don't know you anymore

and these days, you don't seem to want to know me

I try to know you and fail

You just ignore me

I thought we were friends

until you proved me wrong
