Ex wife gave me back her rings

My ex (F30) and I (M31) were together for 13 years, married for 7. We have two kids together. To make a long story short, I came home from work two years ago and she said she was done. She needed to "find herself." I found out there was lots of cheating and lying as well, but that's a story for another post.

Yesterday she was picking up the kids and said she needed to talk. She put the kids in the car and came back inside and with a completely straight face, no emoition, nothing, said "Here you can have these back, I don't want them anymore." I was truly speechless. I just stood there starring at her in shock. I don't know how to feel about it to be honest. Do I hold onto them? Do I sell them and go on a vacation? I really like Mexico haha🤣
