<human>: Obligatory apology if things are all over the place. I'm struggling to keep things straight myself and want to also try to add some back story for comprehension.

5 years ago I made the decision to cut my father out of my life. He is a paranoid schizophrenic, hardcore drug abuser, and extremely physically and emotionally abusive (not toward me, I was unwittingly the golden child. He was abusive to my mother and two older half brothers which I cannot forgive). My earliest memory is of visiting him in prison. There are many horrible things he has done but I don't think it's necessary to go into that much detail.

He has had countless chances to get his shit together but he has never wanted to. He manipulated me into thinking his behaviour wasn't a big deal and when I realised what was happening I was done. I stopped visiting him during school holidays, blocked his number, and told my family that he can never know where I live as I don't want him to come find me. I got myself into therapy to start working through the childhood trauma from his actions. I haven't had contact with him since.

This brings us to last night. I was on the phone with my mother when she mentioned that he's extremely sick and his heart is not pumping blood properly. I didn't ask for details, however she did mention that she is sending my younger brother [15M] to go see him next week as it may be the last time he'll have the chance.

Reddit, I felt nothing when she told me. I'm not surprised he's so ill after the countless overdoses and terrible food he shovels in even though he's a type 2 diabetic. An hour or so later, I bawled my eyes out when I was telling my partner but I was still... Not sad. 

I don't know whether I want to make contact with him. Maybe I'm a terrible person, but I don't want to be expected to have a relationship with him again if he doesn't pass on. I know I would go to the funeral if he does, mainly as support for my little brother. I am at a loss at what to do in the event that he is passing and... I just need some outside advice.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I cut my abusive father out of my life. 5 years later I heard he might be dying and I don't know where to go from here. Please give me your opinions.
