My 3 year old hates me

Co

My 3 year old daughter will only listen to her father and really favors him over me. It’s to the point it’s really affecting me mentally. She’s always been a daddy’s girl and he’s always tried to be extra close to her since his other 3 kids were taken away from him through court. Her dad has tried to do everything for her, some things I’d let him but other things he’d just big boy me and won’t let me. Im assuming their bond is extremely tight. She won’t let me do things for her or help her; help her go potty, open something for her, etc. She has a tantrum if I help her and wants her daddy to help her do those things instead. And I understand she’s trying to be independent but when she does ask for help she only ask her dad even when I’m right beside her and he’s on the other side of the house and I say I can help her. Yesterday she said she hated me and we’ve never taught her that word ever, but she told me she did. Ever since she was a baby she’s always tried to bite and hit me, but won’t do it to her dad. I would say her dad is more strict and consistent with telling her no and I’m more kind but inconsistent with telling her no and we both punish her. I’m disabled because I had a stroke at 16 and haven’t been able to do the things that her dad can. I can’t walk very well, definitely can’t run after her. Majority of the time I have to sit because standing is very painful. Her father has so much fun with her and maybe she just resents me for it? Her father says it’s because I can’t/don’t interact with her as much as he does. I don’t know what I did wrong. I don’t just understand why she hates me and why she’s always preferred him over me all the time.
