One incident (of many) where my ex openly hurt me in public and found it hilarious.
I was with my ex from the age of 18, he was older than me by two years and he was my first ever 'serious' relationship. I was naive, I never knew what a relationship was supposed to be. As with many of the stories posted on this subreddit, he was somewhat nice and sweet to begin with, but slowly he began to change. There were signs that I would dismiss, like how he would call me stupid, or tickle fights turned into me being kicked and shoved (one time his own dog jumped between us when I was on floor and began to growl at him when he tried to get near me - another sign I should have left). I had so many bruises and I would often wake up in the middle of the night while he was asleep crying without really knowing why, which in hind sight must have been my brain trying to tell me I wasn't actually happy.
There was one time we were both out shopping together, we were having a conversation and the subject somehow happened upon how his Dad used to grab him by the scruff of his neck. I didn't know what he was talking about at the time and half laughed asking what he was talking about. He said 'You know!', and proceeded to grab me by the back of my neck hard. My eyes started to water and I was begging him to stop. I said 'Ow! Stop, that hurts!' and through laughter he said 'No, it doesn't'. I kept begging him to let go, and he still didn't and continued to laugh. I eventually clenched my hand into a fist and punched him right in the balls so he would finally lessen his grip. He got angry at me and said 'WTF! Why did you do that?'. People around me looked on in horror at what happened, I got embarrassed and he walked off in a huff because he wouldn't listen to me when I told him he was hurting me and had to literally punch him in the balls in order for him to actually listen. This is one of many physically abusive incidences he did to me to make me feel small, and I was so young and naive that I kept saying to myself over and over 'He didn't mean to'.
Many years later, when we had broken up (after he cheated on me and lied by saying I wasn't 'invested enough' in the relationship), I am now in a healthy and loving relationship, where my current partner would never lay a finger on me and I haven't had any so called 'accidents' with him that I would have to lie to myself about. However, there was only one time where he lightly squeezed the back of my neck, which meant to be affectionate gesture that I ended up shutting down completely. What was a nice day out suddenly turned dark to me. That touch on the back of my neck made me travel back to that moment, my blood ran cold, I could feel my ex's grip around my skin and I'm fighting back the tears and having that horrid sensation of wanting to scream but I'm too much in shock to do anything else. I pushed myself out of my boyfriends arms, explained what happen and from the look of his face he instantly understood that I wasn't okay. He kept his hands to himself, watched me carefully as we took our train back home and waited until I was ready for him to touch me again. We got home, I cried and I went into his arms where I could feel safe again.
I honestly hope that whoever reads this and has come up with the same excuses I did for my ex, that 'he didn't mean it', I really hope you never have to tell yourself that more than once.
