I hope I don't sound to horrible

My ex was VERY abusive to me, while I was pregnant with our child and before hand. Well I'm not going to lie one day I full on snapped and had a mental breakdown. It was literally to the point of where I didn't even know what I was doing. I pulled a knife out of the drawer and came at him with it, I knew for a fact I wasn't going to actually use it to stab him at all, that wasn't my intention I was using it to scare him, to make him back off of me and quit hitting me. Now he tells everyone that I tried killing him I know what I did wasn't right but it was just my breaking point, he would beat me, hold me down and choke me until I was on the verge of passing out, and had even tried smothering me with a pillow. I was scared so my instincts kicked in. The reason I couldn't call 911 is because he had taken my phone away from me and hid it so I couldn't call for help. He had also pulled a gun out and pointed it on me. Of course I got away from it but he keeps making me look bad by trying to say that I was trying to kill him when I was literally just trying to defend myself because I was scared of what he would do. He also has videos of the few incidents where I defended myself and edited the parts out of him hitting me, choking me, and screaming in my face, to make it look like I'm the only one doing something.

I know it sounds crazy and at the time I was only 15 years old.

**i did leave and we haven't been together for a year and he has nothing to do with our baby but for whatever reason he still brings all of this old stuff up even though it actually happened almost two years ago and is completely irrelevant. He constantly tries making me look bad and he brings that up because it is something that could make me look bad.
