Confessing to My Girlfriend About Sleeping With Her Sister Destroyed Their Family

I slept with my girlfriend’s sister once, and years later, that one mistake may have contributed to destroying their entire family. I take full responsibility for the affair and for betraying my girlfriend’s trust, but I don’t know whether I’m responsible for the choices my girlfriend and her sister made afterward, including their physical fight. I honestly don't know whether confessing to my girlfriend was the right thing to do. This happened in 2021, during one of the lowest periods of my life. My relationship with my girlfriend was going through serious problems, and emotionally, I was completely broken. Her sister was one of the few people who kept checking on me. She listened to me, encouraged me, and made me feel like someone actually cared about what I was going through. One evening, emotions got out of control. One thing led to another, and we slept together. It happened only once, and immediately afterwards, I knew I had crossed a line I could never take back. Not long after that, my girlfriend and I broke up. I carried what happened with her sister quietly for years. I didn't tell anyone. I felt ashamed because regardless of whatever problems my girlfriend and I had, sleeping with her sister was completely wrong, and I was responsible for making that choice. I eventually tried to move on with my life, believing that the secret would remain buried in 2021. Then in 2023, something unexpected happened. My ex and I reconnected. We started talking again, settled our differences, and eventually started dating again. The feelings were still there, and I genuinely wanted to do things differently this time. But there was one thing constantly eating me up inside—the fact that I was keeping such a huge secret from her. I eventually decided she deserved to know the truth. I sat her down and confessed everything. I told her exactly what happened with her sister, admitted that I had no excuse, and begged her to forgive me. She was devastated. She stopped talking to me and avoided me for several days. I honestly thought I had lost her forever. Eventually, she decided to forgive me, although I knew forgiveness didn't mean she had forgotten what happened. For almost two years, I believed that chapter was finally closed. Recently, however, my girlfriend confronted her sister about something I had told her during my confession two years ago. Apparently, the conversation became extremely heated. Words were exchanged, emotions boiled over, and things became physical. They ended up fighting, and now their relationship as sisters has been badly damaged. The sister has now blamed me for everything. She told me, "Thank you for destroying our family." Those words have been haunting me ever since. I never told my girlfriend because I wanted to destroy their relationship. I confessed because I felt she had the right to know the truth about the person she was choosing to date. But now I'm wondering if keeping quiet would have prevented all of this. Part of me feels guilty because if I had never confessed, perhaps none of this would have happened. I accept responsibility for the affair, the betrayal, and the pain my actions caused. But my girlfriend chose how to respond to the confession, and her sister chose how to respond to being confronted. Their decision to let the argument become physical was not something I caused or controlled, even though my original actions created the circumstances that led to the confrontation. Another part of me believes I would have been selfish to rebuild a relationship with my girlfriend while hiding something this serious from her. I made a terrible mistake in 2021, and I have regretted it ever since. I am responsible for that mistake and for telling my girlfriend a painful truth, but I am not solely responsible for the choices the sisters made years later or for their physical fight. Still, did telling my girlfriend the truth make me responsible for what happened between them? I'm honestly confused. Did I do the right thing by confessing, or should I have taken that secret to my grave? And was the sister right to blame me for destroying their family, even though the later confrontation and fight were ultimately their choices?
