I told my exes fiancée that her husband raped me

I posted on another subreddit but this is eating me alive because this is still fresh and my close friend is berating me on my decision.

I was sexually assaulted years ago but my emotions are all over the place after rereading old messages. Today I found text messages from my abuser on an old phone that I thought I had lost. I didn’t know how much I had blacked out of my memory until I read them this afternoon and my entire body feels like it’s on fire with the amount of rage I feel. I have years of messages of my abuser texting me a few times each year (the last text in 2023) asking me to console him because of the guilt he felt for assaulting me. This is sick to admit but I had sent him bible scriptures, encouraging quotes, wrote paragraphs about how I forgave him to alleviate the guilt he felt.

I searched his name on google after finding these text and I found out his wedding is soon, this summer to be exact.

I spoke to a friend and she said to only DM his girlfriend, soon to be wife if my intentions were pure. Impulsively I sent her a long DM asking her to reconsider who she was going to marry. I included the screenshots to show her the text of him apologizing for hurting me physically, he never admitted to raping me but to ripping off my nail which was because I was trying so hard to keep him from ripping my clothes off during the assault that he caused a lot of physical damage.

She responded and I’m unsure if I did the right thing. I think instead of telling her because I was looking out for another woman I may have told her because of how angry I am at him for doing that to me.
