Now I understood why I need to use 'with' when I use this phrasal verb as a meaning of 'to finish STH which is mostly the speaker does not want to do'
But I'm still confused by this thing
Why I have to put STH between the verb and particle? Is it kind of just a rule I have to follow?
I have learned that if DO is not a pronoun I can put the DO both of between the phrasal verb or end of.
