Just a straw poll as I'm intrigued. If you are divorced, did you (or your wife) return engagement ring(s) when the marriage ended.
I know that etiquette wise they are a gift and don't have to be returned but personally I returned mine, even though I ended things due to his infidelity and abuse. It was a while ago now but I think my reason was I didn't want him having anything over me.
My boyfriend's ex-wife didn't return hers.
There clearly isn't a right or wrong answer but I'm interested to hear people's opinions and reasons.
