I had a similar situation in August last year. My mother died and my brother made contact with me. He 'seemed' so sensible and caring. I went and talked with him and his wife. Then went back a few months later to deal with the leftovers of my mother's stuff. I honestly thought I was okay with it all.
I wasn't. I didn't even know it was triggering me.
The decision to 'connect' took me back to a level of PTSD that I have not been in for years. It sneaked up on me.
In the last six months
-I have had to seek a new medication
- I had SI daily up to eight times a day
- I have had to take benzos daily when I was at a point where I didnt need them.
- I have not been able to walk into a supermarket for weeks, though this symptoms was not present for three years.
Basically, I confused my brother with the PTSD. He did not look or sound or seem like a monster, but the PTSD Monster was around him and in him. It got me again by having contact with him.
After all of that, I had to go 'no contact' with him again after six months of confusion.
I would encourage you not to go. Not to contact him. Not to see him. You may be confusing him with a human who needs compassion and love from YOU. This is your caring/giving nature. He will get care from the people looking after him.
If you go, you will give him something out of your heart all over again. You are loving. He knows this. That's why he felt entitled to abuse you.
Do you want him to feel entitled again?
Can you do some rituals? Can your burn something, bury something, punch something, write something.
I also thought it would give me closure. It did. But it also gave me back severe PTSD symptoms.
It is possible you will get closure from seeing him. But I dont know if you will feel some sense of satisfaction seeing him visually in person, in a state of dying. I did not want to give my mother that 'supply' so I did not see her when she was dying.
Can you go after he dies? If you do go, please take care not to engage in his BS conversations about loving you. If knew how to love properly he would not have done what he did. Males who have sex with their sisters do not know how to love properly. They are fkd up. They are pretenders.
Sorry to get involved and make it personal.
Basically, bottom line. 3 options I can offer. Dont go & work on things like rituals. Go after he dies. Go and see him but dont stand close or talk closely. Show him strong boundaries and tell him lots of "you're not allowed".
I feel for you. I am sorry.
