Take care, sweetheart (6)

I believe the answer is:

steady

This clue is a double definition.

'take care' is the first definition.
('steady' may be said to tell someone to take care)

'sweetheart' is the second definition.
(both can mean a romantic partner)

(Other definitions for steady that I've seen before include "not easily excited" , "Not wobbling" , "Stayed (anag.)" , "date seen regularly" , "Slow and ... wins the race" .)

I've seen this clue in The Times.
