I am in agreeance with everyone who said to ignore. It may be all sweet letters and I miss you right now but i guarantee you in about 2 more months time when they see its doing little to bring you back to the kingdom hall that the same little girl and whoever else put her up to it will be ignoring you and acting like you don't exist out in public.
Carry on with your fade and making a new life with new friends who aren't just trying to get you to do what they want.
