Man I've been posting here a lot, I'm sorry y'all. :( I'm just curious because this is a question I get a lot, and I usually reply that it was three years ago, and that we were on separate paths. I feel like that should be enough, but some of these dudes are VERY intent on knowing the specifics.

So here's why I'd rather keep silent about it:

As some of you may know, I was stuck in a six year relationship (my first "actual" relationship) with a guy who I thought was "safe" because he was nerdy. Looks wise, I was far out of his league. Our first year was okay, but after the second, his true side began to show and I'm still mad at myself for letting it extend for so long. I should have known his fucked up home life with an abusive, playboy military father was a gigantic red flag. But I was a naive PickMe.

Year 2 was the first time he cheated (with a friend of his who was still in high school because she was a "conquest" he'd forgotten about...his words). He was 21, she was 17. It was also the first time he laid hands on me by twisting my wrist extremely hard because we had an event to go to and he refused to leave the house without a couple of his grandmother's Vicodin pills (to take for fun). He also chain smoked due to his BFF doing the same thing, and when I said it bothered me he stopped for one week before resuming.

But I think our last two years were objectively the worst. By that time, we had moved in together, since he pressured me into it because "oh my grandma is kicking me out, she says she can't handle another person in the house." Mind you, he uprooted her peaceful retirement with all the bullshit he was doing, so I'm not surprised. He was kicked out of his parents' house for being a "danger" to his sister and two half sisters. I later on found out that he may have molested his bio sister, when she had told me he often said that he wished I looked more like her. I look like a woman, and she has the body of a 12 year old girl(inherited from their mother). Obviously I would have never been able to match up to that, but it explains why he loved going for petite/thin girls. The manic pixie ones were his favorites, or ones that looked barely legal.

Our apartment life was miserable as fuck. Every three months he had decided he was "bored of me", and would kick me out of my own damn apartment just to bring a girl over to fuck in our bed or in our living room. And I had actually overheard him and a girl he had been casually dating fucking because they were moaning so loud. That shit messes you up. The only reason why she broke up with him is because one day I happened to be home first, and I locked myself in the bedroom and refused to leave, and I could hear her whispering that this wasn't cool and that she was ending this. She was perfectly aware that he was still "sort of" with me. He turned our relationship into an open relationship without my permission. Sometimes I still remember the night he came home hopped up on cocaine, proudly bragging that he had fucked the hottest stripper at the strip club he and his buddy went to. He waited to meet her after her shift, and he would not shut up about how she had the most beautiful Southern accent. In total, he must have cheated maybe 15 times while I was faithful and did everything a girlfriend should do.

He would also get terribly drunk and tell me the nastiest things. I can still recall the time when he was mad that I didn't want to have children with him, and he said "I would love to just tie you up in front of your parents, slit their throats, and then rape the fuck out of you. Maybe then you'll give me a child."

When he was back in the honeymoon stage, besides the constant sex(for his pleasure), he would ignore me for hours to play League of Legends or some other MMORPG, leaving me alone in our bed. I would wake up to go to work and still find him playing games, on the brand new Playstation I bought for him.

But besides the mental/emotional abuse, the worst was the physical. He became belligerently drunk one night, and choked me to the point of blacking out *twice*, just because I was not as thin as I had been five years ago. He would deliberately starve me, weigh me, and track me to the gym to make sure I was working out. I was not overweight btw. I'd just grown into my hips that I got from my mother.

The last straw was when we were living at my parents' house after losing the apartment, and that particular day, I was excited because I'd just gotten another raise, and a promotion at work. I finally had money to fix my dying car, because he sure as shit wouldn't drive me to work. He was drunk by the time I came home(he was unemployed at the time and my parents had been pressuring him to go looking for jobs as a stipulation for letting him live with us). I told him about my day at work, and instead of congratulating me, he got angry that I wasn't using the money on him, and attacked me. My mom heard us both hit the ground from downstairs, and she came running upstairs to find him pinning me down, his fingers pressing hard into my jaws to shut me up from screaming. She had been holding the phone, and out of shock and rage, she smacked his head with the phone, and yelled for my dad, who had luckily just come home. My dad's a big guy, and when my ex tried to make a bolt for the door to escape, he tackled him and held him down while my mom called the cops. He was arrested that day, but because of white privilege he was released in three days. He manipulated me into not pressing charges because my bruises were "self inflicted" and that I must have gone into the bathroom and beat myself up to show the cops.

This is just a very small snapshot of the torture I went through, and while therapy has helped a ton in getting through a lot of the PTSD I got, I do not want to divulge ANY of this to a new partner. They do not need to fucking know, because god knows how depraved some men are.

TL;DR: What is a proper answer to get the point across that the past relationship ended, end of story? I do not want to divulge the entirety of my incredibly abusive LTR.
