Which question is correct? Please help me as I'm completely confused.
Tony ________ to have children until his little daughter was born. After she won his heart, he decided he wanted a big family.
A. didn't want
B. hadn't wanted
This is a multiple choice question from Understanding and Using English Grammar Workbook, 3rd edition by Betty Schrampfer Azar. To me, both A and B seem correct and I don't know which option I should delete.
