Lavished love (on) (5)
I believe the answer is:
doted
'lavished love on' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for doted that I've seen before include "Was weakly affectionate" , "Was excessively fond" , "Showed (excessive) love" , "Lavished affection" , "was foolish" .)
