I never beat her. The question you were aiming for is "Do you still hit your wife?"

It demands a yes/no answer and thus always appears to be an admission of guilt. Your question leaves it open to answer any way you like.

Your answer still works for your formulation of the question, "I never hit her."

It's not that it's a true Catch 22, it's just leading and begs the question.
