I, and practically every JW, at one time sincerely felt the same way the elder described. JWs don't understand the concept of unconditional relationships. They are trained not to. They are trained to think their response to your DFing is a loving one.
When I came to my senses years later, my cousin was the first person I personally apologized to for my cold-shoulder treatment during his time as DF'd. I explained that was my training and that I believed my course was one that showed respect for God and his name. What a joke...
Maybe your elder buddy will see the light eventually and pay you an apologetic visit. When he does it will be a great day for you. Either way, don't let his actions ruin the rest of your life.
