Doesn't stay on even terms (5)

I believe the answer is:

quits

This clue is a double definition.

'doesn't stay' is the first definition.

'on even terms' is the second definition.
(as in 'call it quits')

(Other definitions for quits that I've seen before include "Even - leaves" , "Abandons" , "On equal terms" , "Leaves - all square" , "On even terms again" .)

I've seen this clue in The Irish Independent and The Globe and Mail.
