Dsis lives abroad and has done so for many years. She has 2 dc. When dsis children were small I never missed their birthdays or Christmas always sending gifts. I never received a thank you letter/email/message from the dc although dsis would say thanks. I stopped sending gifts when they reached early 20s.
Dc are now adults in early 30s. Dnephew is married with 2 dc of his own and lives near dsis. I sent gifts when the babies were born and for christenings/birthdays/Christmas - again never a thank you from Dnephew although dsis says thanks. I recently sent some gifts which again dsis has thanked me for.
About 2 years ago Dsis and Dnephew have big falling out but reconcile after some months. Dsis does not see as much of Dnephew and his children as she would like and moans to me especially that she has to hassle him for photos. In most recent call she says she has hardly seen dnephew/wife and children for weeks.
Last night Dsis send me a photo of the little ones which she's obviously been sent by dnephew. Then she says why don't I message dnephew and/or his wife on whatsapp.
AIBU to think they should message me ? Why should I make the effort ?
