My parents divorced when I was in the second grade. Dad was always self-centered and didn't have much involvement with us after that. He didn't abandon us, he was responsible with child support and remembered our birthdays and Christmas, but he lived in another state and rarely visited. He was too busy with his bachelor lifestyle. After I grew and married and had kids, he still had no involvement in our lives despite years of invitations. He only met my oldest daughter once when she was little and never met my youngest until she was 18. He's not a horrible person, he's not mean or abusive, but he's completely self-absorbed and a total hypochondriac. He's now in his 80s and completely alone, except for me. My two brothers have washed their hands of him and their kids hardly know him. We live in different states, but I visit him a few times a year. He frequently sends me looong emails about all his struggles and problems, repeating the same things over and over in great detail. He almost never asks about my life or my family. His physical and mental health is quite good, but his emotional health is terrible and he struggles with chronic anxiety and depression. I know I'm facing a future of having to care for him, because there's nobody else to do it. But I really don't want to! He was never there for me or my family and I resent having to be there for him. But what else can I do?
