When I first addressed the matter I was told she needs to “process it” and “deal with the other things going on in her life right now” but that was two years ago and still not a peep from her. She stopped talking to me because I called her out in her comment section after she refused to speak about it in person multiple times.

Perhaps you’re sister stays away not because she has forgot, but because of the shame that eats away at her knowing what she did to you. In addition, the person who molested her may potentially be someone really close to you all. Someone within the family circle, and that’s why she only visits when necessary.

What you need is a LICENSED therapist. Talking to your sister who has made it clear she doesn’t want to discuss anything with you isn’t going to help you. Focus on YOUR healing and moving forward at your own pace otherwise you will be stuck in a horrible cycle of having expectations that aren’t and will not be met. It sucks and I am so sorry you had to endure something so horrible BUT it is clear you will never get closure from your sister. At this point you should think about moving on
