To fade properly you need to be not known as a JW at all
if you allow them back into your life you will postpone it
on the other hand if you say anything like you are not known as a jw they may announce you as no king a jw which would be a fade interruption
you need a good few years of no contact whatsoever
if you have had contact it resets the clock as it were
unless your not bothered by shunning then just go ahead and let them announce your no longer a jw
my advice is always avoid any contact with elders for a few more years then you will succeed in fading and even if it was found out you did something like a disfellowshipping offence then you still wouldn’t be shunned
