I never realized how much of a hater my stepdad was until today...

This just a rant, but feel free to comment, I don't mind.

So just a short back story, my stepdad has been in my life since I was a small child. Growing up I never really was interested in forming a bond with him because I was more concerned with bonding with my biological dad. I am now in my late 20's , so he's pretty much been around my whole life. He has this issue where he always feels he's right about any and everything and if you try to correct him or prove him wrong in anyway it always ends in an argument, he never apologizes even when he's wrong. Idk how many times we've butted heads because I've called him out on his bs. He comes off as this "nice" guy, but in reality, he is the fakest person I've ever f'n met and it literally was confirmed today.

So, a few months back I decided to move back home to save money and finish school. A few days ago I overheard a conversation he was having with my younger sister and pretty much the conversation started being about me, He pretty much told her about a past mistake I made as a teenager, but he totally twisted the story and made it seem like I was just some type of Jezabell. I wont go into detail because it was something personal that I regretted doing. But I am now grown and obviously can see that I was in the wrong for it , but my point is... it wasn't his business and he just sat there and told that MY LITTLE SISTER about something that had nothing to do with him and the fact that it was so personal I felt that it was not his right to say anything about it because again, it was not any of his business to tell. If I wanted her to know about it , I would've told her myself which is what I eventually did today. While having the conversation I found out that he had been talking a bunch of bs to my sister about me and the whole time she was telling me I was wondering what animosity this fool must have against me when I have never dragged him or told any of his business to anyone, especially not my siblings. I could've dogged him out to my siblings or pretty much anybody about how he hasn't been employed for the last 13 years and he will watch my mother struggle to pay the mortgage and provide , while he sits on his ass all day everyday or how he's pretty much jealous of his own kids for having a better life than he did. But , I'm just simply not that type of person because I'm not fake and don't smile in anyone's face and talk mad crap about them behind there backs. But with I learned today at this point , I simply dgaf about his feelings , his ego gets hurt anytime anyone mentions why he doesn't work and will argue you down about that as well , me and my siblings have asked on different occasions and it always resulted in an argument.

Again, I don't understand where all the hate from him came from and I am kind of annoyed about it. I wanted to address it right then and there, but I already knew it would result in argument and I didn't want to spook my siblings (they are a lot younger than me and don't like conflict). Instead I just talked to my mother about it and she said she'd talk to him because she felt that wasn't okay. but i doubt that'll change anything he's always been this way. I feel bad because when I didn't live with them my siblings would always wonder why I'd only come around maybe once or twice a month and its definitely because of him. I always hated being around him cause its so hard being around someone like him.
