I have two adult DC one has so much, ie big house on the coast, 3 kids, loving husband, plays golf etc, the other younger one, alone and hard working. Older DC treats younger DC like a stranger and with undeserved contempt most of the time. No conversation, grudging and late birthday and Christmas presents, almost as if they aren’t there. I am so sad about this. I am a young(ish) widow and am seriously considering leaving the bulk of my money to younger DC due to the mean attitude of older DC. AIBU?
