Why am I expected to love my mother?

Assalamu Alaikum. Why is everyone acting like I have to love my mother? I don’t. She never liked me, so why should I pretend? I can’t make my haq halal because I don’t accept being forced to feel affection just because she’s my mother. From the moment I was born she didn’t show love. She used to say she only had children because of social pressure and that she never wanted marriage. My childhood was full of beatings and psychological abuse. Even at 24 she would still hit me. She had unrealistically high expectations. I had to be top of the class - anything less meant being beaten. I wasn’t allowed to play; I either studied or did housework. She pushed me into a career she wanted just so she could brag, “My daughter studied.” She always looked down on other girls, calling them cheap or disgusting for caring about their appearance and not studying. Ironically now she praises those same girls as social and kind even though they didn’t study, while she calls me antisocial and a failure despite my degree. She doesn’t see that she created this. She never wanted me to have real friends and controlled my relationships. I wasn’t allowed to talk with guests; I had to stay in my room or serve. I was raised to be quiet - speak only when spoken to - because saying the wrong thing meant punishment. That made me seem shy, but it wasn’t natural; it was taught. As an adult it’s very hard to undo. I struggle with trust and I don’t have a circle of friends. Even now she makes life miserable. She didn’t want me to marry; she wanted me by her side forever. She tried to ruin my relationship and even admitted making dua on my wedding day asking for an accident so I wouldn’t be married. She told me she doesn’t want to look after my children and discouraged me from having any. I had imagined maybe my kids could visit their grandmother sometimes after I got married, but after hearing that, it’s impossible. She has never apologized. She denies everything and truly believes she was a good mother. Everyone else loves her and thinks she’s kind - they don’t know what she’s really like. Now that I live far away she tries to be nicer, but I can’t like her. I can’t forgive what she did; it broke me too deeply. The only reason I still keep contact is cultural and because Islam teaches ties of kinship (silat ar-rahim). Otherwise I would cut her off completely.
