So this was a couple of years ago but it still regularly gives me a sinking feeling and I’m not sure if I was right or wrong. A couple of years ago I was engaged and it was not a healthy relationship. Looking back on it it was actually pretty horrible but I didn’t know how to get out of it. Eventually it was forced on me because he (liked to drink a concerning amount) woke me up in a drunken rage, accused me of cheating (I wasn’t) and got violent. He was shoving me and screaming at me and eventually threw a 2x3’ framed painting at me hard enough to break the frame through bubble wrap. I left in the middle of the night and only came back for my stuff. I took photos of al the bruising and the messages he sent me harassing me for the next few weeks. My question is though should I have reported him for domestic violence? He always had issues he would regularly scream at me enough to bother the neighbors, but that was the worst physical incident. It gives me anxiety and stomachaches to think that it’s possible that someone else could go through it with Him too because I didn’t report him. But with everything else I was dealing with I didn’t think I could handle legal action as well. 
What do y’all think? 

TL;DR ex fiancé was abusive and I feel responsible for people he’s awful to in the future
