My cousin's dad just sent him a baby gift with a card. He only addressed the card to my cousin's wife and granddaughter. For some stupid reason, he can't even write his son's name on the card to congratulate.
Why do they make a difference between relatives that have left the JWs and those that have never been JWs? Mine do the same, obviously because they want to punish your cousin for daring to be different. Act of love, who are they trying to kid!
They seem a very fanatical, controlling family. You and your cousin did well to leave. It's very hurtful but all I can say is you are well rid of these toxic people.
