AITA for reminding my mom that she disappeared for six years?

My(18) mom and dad divorced six years ago. Her new husband didn’t want her to see my dad and so she let my dad have custody of me and didn’t exercise visitation.

She contacted us last month, saying she had divorced him and would like to reconnect. Dad told me it’s up to me so I said ‘Why not?’ Things have been kind of awkward between us. Obviously I’ve changed a lot since last time she saw me.

When she came over yesterday, I was reading An Offer from a Gentleman. My mom said ‘You’re too young to be reading these toxic romance books.’ I just stared at her and said ‘I was 12 when you disappeared six years ago. I’m 18 now.’

She spluttered for a moment and then told me there is no need to use that word, that she made a mistake and there is no reason to throw it in her face.
