Single and not stuck on anybody? (10)
I believe the answer is:
Here is my best explanation:
'single' is the definition.
'stuck on anybody?' is the wordplay.
'stuck' becomes 'attached' (I've seen this before).
'on' is a charade indicator (letters next to each other).
'anybody?' becomes 'un' (I am not sure about this - if you are sure you should believe this answer much more).
'attached' after 'un' is 'UNATTACHED'.
'and not' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
(Other definitions for unattached that I've seen before include "single", "Not joined", "Single", "Not belonging", "Not married" and "independent".)
