也对.
I'm considering whether to help the girl or not .或I'm considering whether or not I should help the girl.
The woman got divorced last week.(got去掉也可以,但有got的说法更普遍些.）
When did you get divorced?(When did you divorce也可以,但有get的说法更普遍些.）
divorce的用法与marry相似:
通常不这样说：Whendid you marry?Has she married?
通常这样说：When did you get married?Is she married?
