Maybe needing company to advance money, as you'd say (8)
I believe the answer is:
lonesome
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for lonesome that I've seen before include "Sad and lonely" , "Solitary (chiefly US)" , "Solitary (mainly US)" , "Isolated" , "Solitary and sad" .)
