I am quite a sensitive person so not sure if IABU.
I'll keep it vague so not too outing.
I'm a carer for a family member (older relative, not my chid or spouse), we have a family whatsapp group where we chat/arrange thing etc. I sometimes post messages about my relative, how they're doing etc and this same person always reads but chooses not to reply. I get that they are a busy person (aren't we all!) but they've no kids, so just themselves to worry about. They find time to share photos of holidays or recent purchases etc, but no time to comment on my poorly relative.
It drives me mad and really upsets me. AIBU?!
