free love

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

'without commitment' is the definition.
I can't tell whether this defines the answer.

'not bound to come to nothing' is the wordplay.
'not bound' becomes 'free' ('free' is the opposite to 'bound').
'to come to' says to put letters next to each other.
'nothing' becomes 'love' (love means zero in tennis).
'free'+'love'='FREE LOVE'

'it's' is the link.

Can you help me to learn more?

(Other definitions for free love that I've seen before include "Promiscuity" , "General Congress" , "presumably ruling out bondage" .)

I've seen this clue in the Evening Standard.
