New girl meets head of Roedean? I don’t believe it! (5)

I believe the answer is:

never

I'm a little stuck... Click here to teach me more about this clue!

'i don't believe it' is the definition.
I can't tell whether this defines the answer.

'new girl meets head of roedean?' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'girl' becomes 'eve' ().
'meets' says to put letters next to each other.
'head of' says to take the initial letters.
The first letter of 'roedean' is 'r'.
'n'+'eve'+'r'='NEVER'

Can you help me to learn more?

(Other definitions for never that I've seen before include "Not ever" , "Not in a month of Sundays" , "At no time in the past or future" , "Under no circumstances" , "Strong negative" .)

I've seen this clue in The Times.
