Maria visited her daughter many times

[Bassim]

Have I made any mistakes?

Maria visited her daughter many times and noticed that Jo never kissed or hugged her children or showed tenderness. She seemed to be keeping a distance from them as if they were strangers. Maria asked her what had happened, but Jo was evasive and replied curtly that she was busy with her work didn't have time. Maria shook her head, dissatisfied with the reply but didn't wish to pry. Jo had recently divorced and she feared that her daughter projected her own frustrations onto her children.

was busy with her work and didn't have time.

I'd probably write "dissatisfied with the reply but not wishing to pry."
I'd put a comma after "divorced", as well as changing "she" to "Maria" for clarity.

I might change "tenderness" to "affection", although that's more of a stylistic choice.

I hope that's just a writing exercise and not a true story. It's very sad.
