Leaving, very rich, getting dumped (9)
I believe the answer is:
offloaded
'dumped' is the definition.
(I've seen this before)
'leaving very rich getting' is the wordplay.
'leaving' becomes 'off' (as in 'I'm off').
'very rich' becomes 'loaded' (I've seen this before).
'getting' says to put letters next to each other.
'off'+'loaded'='OFFLOADED'
(Other definitions for offloaded that I've seen before include "Got rid of" , "Dumped" .)
