How one who lacks decision is caught (2,3,5)
I believe the answer is:
in two minds
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for in two minds that I've seen before include "Wavering, undecided" , "The outcome is uncertain" , "where similar ideas may be foolish or clever" , "like Dr Jekyll at times?" , "Torn" .)
