Feeling of anger from pledge to marry? Run for good (10)

I believe the answer is:
enragement
'feeling' is the definition.
(enragement is a kind of feeling)
'anger from pledge to marry? run for good' is the wordplay.
I cannot really see how this works, but
an anagram of 'anger' is 'enrag' which is within the answer.
This may be the basis of clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
I've seen this clue in The Guardian.
