Is AUTHOR wrong in the post ? POST : Heyo. So a long time ago, my parents divorced. I got to go with mom, while my dad didnt even get visitation after failing to appear in court. Dad never phoned, Dad never sent gifts, and even though I moved around a lot with mom, I kept in touch with Dad's side of the family and he still never made any effort to talk.

Fast forward to me in my late teens, I finally talk to him in a tearful "reunion". He's sick with diabetes and he's slowly losing his eyesight. Our talk is short lived as he immediately starts talking trash on my mother's side of the family. I decide to not spend much more time with him.

Fast forward to me being a young adult, 23-ish, and I've completely grown to resent him. He's sick and dying a slow death, completely blind and having to do at home dyalisis.

I was struggling with finding a job and unfortunately hit my safety net, being forced to live with my dad's side of the family. Now I'm expected to help care for a man who never made an effort to look like he cared for me. He jokes about how I'm respectable because I'm not a "flamboyant gay", I'm just a "regular gay".

Normally, I'd call this cut and dry, but, my dad's side of the family still obviously cares for him, especially my Grandfather. I understand the prospect of outliving your offspring is heartbreaking... but when my grandfather asks me to think of my dad, I feel too hurt by his absence in my childhood to even consider it. 

I'll help do a thing for my Dad occasionally, like driving around and being an errand runner, but I make sure I air my disdain for it every time. I know for a fact that I can get very petty about this. My grandpa chides me for not keeping an open heart, but I feel like I've already tried to open up once and all my Dad did was starting spitting venom.

It's gotten to the point where I'll openly mock my Dad to his face, and my last contact with him I called him a shitbag and told him he's a useless deadbeat who is getting his karmic justice. He called me smelly.

My grandpa is hurt that my Dad and I cannot get along anymore, but it was my belief that we never really got along at any point in our lives.

So I'm mostly worried about my grandpa in regards to this question, but, AITA?
