I am drowning in guilt…

I met someone online and within that same weeek, they wanted to move very fast. I was naive, so we did. At the time, I had casual flings and I had ended them. There was one guy, however, and I don’t remember the specifics of it bc my memory blacked out some of it I think. I ended up at his place and he tried to sleep with me but I ended up pushing him off and screaming. It was traumatic and I remember going home crying. I wasn’t serious about dating someone but I started a long term relationship with the person I met online. It was love but it was physically and emotionally abusive at times with gaslighting, stalking, and just I couldn’t take it anymore.

i feel so much heaviness on my heart. I feel guilt but I also don’t even know if I should tell this person what happened tbh
