Stops to give me a hug, which makes it better (6)
I believe the answer is:
emends
'stops to give me a hug which makes it better' is the definition.
The answer and definition can be both related to change as well as being verbs in their -s form.
Maybe you can see a link between them that I don't see?
'stops to give me' is the wordplay.
'stops' becomes 'ends' ('end' can be a synonym of 'stop').
'to' means one lot of letters go next to another (I've seen this in other clues).
'give' indicates anagramming the letters (I've seen 'giving' mean this (the letters give the letters for another word)).
'me' with letters rearranged gives 'em'.
'ends' put after 'em' is 'EMENDS'.
Can you help me to learn more?
(Other definitions for emends that I've seen before include "Makes corrections in written or printed copy" , "Send me (anag.); corrects" , "Makes improvements or corrections" , "'Corrects, puts right (6)'" , "Alters, corrects" .)
