This person cried stupidly about love being 'ordinary' (8)
I believe the answer is:
mediocre
'ordinary' is the definition.
(I've seen this before)
'this person cried stupidly about love' is the wordplay.
'this person' becomes 'me' (I've seen this in other clues).
'stupidly' indicates anagramming the letters.
'about' is an insertion indicator.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'cried' with letters rearranged gives 'dicre'.
'dicre' going around 'o' is 'diocre'.
'me'+'diocre'='MEDIOCRE'
'being' is the link.
(Other definitions for mediocre that I've seen before include "Commonplace, not distinguished" , "Run-of-the-mill" , "Fair, middle of the road" , "Average (but poor)" , "Rather inferior" .)
