A romance eventually finished, but very nice (6)

I believe the answer is:

lovely

I'm a little stuck... Click here to teach me more about this clue!

'very nice' is the definition.
(I've seen this before)

'a romance eventually finished' is the wordplay.
'a romance' becomes 'love' (I've seen this in another clue).
'eventually finished' becomes 'ly' (I can't justify this - if you can you should give a lot more credence to this answer).
'love'+'ly'='LOVELY'

'but' acts as a link.

Can you help me to learn more?

(Other definitions for lovely that I've seen before include "Great!" , "Admirable" , "Beautiful or delightful" , "Fair" , "Very nice -- coy elm (anag)" .)

I've seen this clue in the Evening Standard.
