Please advice which is correct N1 or N2?
1. My obsession for cars is becoming more and more addictive.
2. My obsession with cars is becoming more and more addictive.
I think "with" is better because of "to be obsessed with". May be I am wrong though.
Thanks in advance.
'Obsession with' is correct.
You can also be obsessed by, as well as obsessed with.
