Seeking Guidance Regarding My Father's Behavior

As-salamu alaykum, I'm reaching out for some advice and hoping to get a better understanding of my situation. Recently, my mother underwent cataract surgery, which she wasn't too keen on, but my father encouraged her to go through with it. Since the surgery, almost two weeks now, my father's behavior has been really concerning - he's been distant, hurtful, and verbally abusive towards both my mother and me. He says things that are really hurtful, gives us the silent treatment, and creates a lot of tension at home. My parents barely talk to each other now, but I still try to interact with him since we live together. My maternal aunt also lives with us, and she's been a big help with cooking meals, while I handle other chores. The other day, he asked me to tell my aunt to wash his clothes, which made me feel uncomfortable because I don't think it's right to treat her like a maid. So, I didn't pass on the message and planned to do it myself later. When he saw that his clothes weren't washed, he lashed out at me verbally. Honestly, this kind of behavior from him isn't new - growing up, he's often been emotionally harsh, although sometimes he can be kind. Unfortunately, in the past, he has physically abused my mother a few times, which is really troubling for me. Given this history, I'm struggling to understand whether my feelings about their relationship are valid or not, and I'm finding it hard to cope with the situation. I love my father, but I'm getting this weird feeling about all of this, and I'm not sure what to do. He's a good father in many ways, but I'm really confused. Please help me understand what I'm going through and guide me on how to deal with this situation. Jazakum Allah khayr.
