Giving the ring back - Settle a debate?

[ChicJoker]

Hypothetical, debating a friend. If a couple are engaged and then breakup, should the ring be given back? Does the value of the ring influence your decision?

This.

Occasional exceptions for family rings with sentimental associations etc.

What he would do with it? Re-propose to someone else with it?
He breaks up - she keeps it, for the time wasted 🙃

I wouldn't, but only because we bought it together and have always shared our money 100%. If my other half had bought it, or it was a family ring, I'd absolutely return it!
