Input: I'm M18 and moved in with my dad and stepmom back in November. This is going to need a bit of background though I think before I start.

My dad has always been a drug user, from very heavy stuff back in the day to now only weed and alcohol. He's aggressive and abusive but also caring. Very narcissistic and outright stupid sometimes, but also smart and logical other times. He's very unpredictable but he's always been kind to me. My mom's side of the family, who I've spent most of my life with, all dislike him greatly. I've always defended him as much as I can, but I definitely understand and agree with them, to a degree.

Like I said above, my dad is unpredictable. An accurate metaphor would be a sparkplug. Since November, he's gotten progressively worse and worse, consistently yelling at my stepmom and myself for the dumbest things, like not putting enough creamer in his coffee or no mustard on a sandwich. This is seriously the things he gets so mad about, he has to leave for several hours and come back that night and "apologize". My stepmom and I discuss him frequently when he's gone and we have no idea what to do. He doesn't have a job, except from Uber-ing occasionally, and my stepmom works 40+ hour weeks at a restaurant to support us. I help out as much as I can with my financial aid, mostly by paying certain bills or just taking care of myself and taking that burden off of them.

My dad is still kind to me, but it feels a bit backhanded. He bought me an expensive game (AC Odyssey Gold Edition) for Christmas, which is awesome, and he buys the food I like and treats me with respect, but he also kicked in my door because I was struggling with my counselors to get a schedule at college. He fixed it afterwards and apologized, and we talked about it all. The next morning though, he barges in my room at 7 in the morning and yells at me for the exact same thing, despite having an understanding the previous day!

Recently I've just stayed in my room and kept it locked. I go out and get food when he leaves, and I talk very minimally to him. I feel like I can't do anything in this house without getting yelled at or even potentially hit. I always hear him yelling through the walls. He gets mad I don't talk to him and spend time with him, but what am I supposed to do? As a result I barely eat and sleep and live in constant anxiety about what he's gonna do next.

Am I the asshole Reddit? I don't know at this point. I feel justified in not giving him the satisfaction of being a dick and still getting what he wants (time with me). But I also feel really awful because he does a lot for me and doesn't ask much in return (unless he's being a massive prick). So please, let me know.

I had to reformat this post, so some details might be missing. I don't really have any other place to go, or if I do move, I wouldn't have the privacy and freedoms I do here (like having to sleep on a couch).
