Aitah For Pushing My Uncle After He Was Insulting Me And Threatening To Beat Me Up?

I am a 27 female. My uncle is in his sixties. I’m staying with my mother and grandmother for the last two weeks, because I’m back in my home town and wanted to spend some time with them. I got really, really sick, very bad flu or virus.. my grandma got sick as well and my uncle came to stay with us and help, because my grandma is 100 years old and her age combined with the virus requires lots of care. It was too much for my mom, because she also had to take care of me.. I had really high fever and couldn’t get out of bed some of the days. Now I’m feeling better, but my uncle is still here, taking care of my grandma while my mother is working. My uncle is a person with huge ego, always talks to people like they are less than him, he’s disrespectful, very bossy. Expects people to treat him like he’s in a higher position than everyone else. He’s also a tall, big man with a very deep voice and I think people are intimidated by him. I can see that he’s making other family members feel uncomfortable when he’s acting like he’s a king and people are his slaves, but no one says anything. Except for me. I do say things like “don’t do that/ that’s not okay/ don’t talk like that” when he’s being rude or out of line. He hates that I don’t keep my mouth shut and we’ve had some conflicts before. This time everything between us was fine, he was nice to me, I was nice to him. Except for a joke he made about me dying, which I did not appreciate, told him “don’t say that”, he ignored me and I left the room. Didn’t think too much of it, he has a dark sense of humor and you can’t stop him from saying anything he wants to say. The next day he was complaining about my mother not taking good care of my grandma, which is bullshit - she wakes up a few times every night to check on her and help her if she needs water/ medication/ going to the toilet. So I said: don’t talk about my mother like that. I wasn’t raising my voice or being rude, I was just defending my mom. He said: stay out of this it’s non of your business. I said: I’m just not going to allow someone talking about my mother like that. He said: seems like you haven’t been hit enough in your life. I said: what did you just say?!. Then he threatened me, I don’t remember his exact words, but it was something about him hitting me. I said: did you just threaten me?!. He said: I did not only threaten you, but I’m also going to do it, because you’re a stupid bitch. I told him to take back the things he’s saying immediately and he said: I’m not going to, because it’s the truth - you are a stupid bitch. I got very angry and pushed him. ( I’m very skinny and weak after the sickness, so I’m sure I caused him zero physical pain.). Then he kicked me like he’s kicking a dog. He is very strong, he’s like a bear, so it was very painful, my leg still hurts. I got scared that he’s really going to beat me up and screamed. My mother entered the room, I told her what happened, she defended me. He said he’s refusing to apologize, called me a stupid bitch one more time and said that just kicking me wasn’t enough, because I deserve more. Now I try to avoid him, because I don’t feel safe. He’s also talking about people deserving to die a lot lately, which is creeping me out.( our neighbors told him to move his car and he said that their place is in the graveyard and that he means it) tomorrow there’s going to be family gathering at our place, so I was thinking to confront him in front of them, so he doesn’t hit me. I already told my cousin and his wife the whole story and they are on my side and are being supportive. I’m just not really sure if I have the right to stand up for myself, because I did push him, before he kicked me. My mother is acting like nothing happened and that’s making me very confused. All of my friends are telling me that this is a very serious situation and are on my side as well, but I still dont know if I have the right to have a problem with what happened. … it’s not the first time he’s complaining that my mom is not doing a good enough job with my grandma, he criticizes her for everything. He thinks it’s unfair that he has to do so much for my grandma, because it’s too much for him and he’s stressed. But my mom takes care of grandma for years, which is not an easy task. A hundred years old person is almost like a baby, needs care and attention almost 24/7. So yeah… am I the asshole?
