If We Decide Not to Get Married Who Gets the Engagement Ring?

The engagement ring goes back to the person who owned it originally.  Here's a list of who gets it:

• If the groom bought the ring and proposed with it, it’s his. 
• If the bride bought the ring, she keeps it. 
• If the ring was a family heirloom it goes back to the family. 
• And if the groom tells his former fiance to keep it, then the bride can keep it, but to avoid a lawsuit I’d get that in writing.
