Is it normal i don't love my mom?

When I look at her I don't feel hatred or even dislike. But I can tell ya what I feel for her ain't love. She's not a bad mom but she's not a good one either. She is okay one. There is plenty room for improvement. I know most moms are like that but mine is very aggressive and controlling. I feel like she is just a familar face, like you hold a connection to her and know her. Have you any you had that person in your life when you say you love them but really don't understand what love means? Also in my mind I don't call her mom but "fat wife". I know that's rude but I don't know. I just do.
