Any contact from the local Jws from now on isn't going to be for your 'spiritual' welfare but to sow fear into those remaining in the congregation that you have left.
Other posters have mentioned F.O.G. on here and the elders will try their hardest to ensure you are made an example of, if you let them, to ensure a fear of isolation is put into those who may also feel they can fade away; to remind them that they are obliged to tell on their brothers and sisters if they see anything untoward happening; and to remind them that continuing to be your friend would make god cry...
If you want to be party to their F.O.G tactics then meet with them. If you want no further part in their cult then tell them to F.O.!
