What do yo do with gifts your ex-boyfriend gave you? 

You like them very much but you cannot wear/use them anymore???????? (well it's more like you don't want to wear/use them...) I have a pair of Tahitian pearl earrings and necklace that my ex-boyfriend gave me and I no longer wear them because I don't want to be reminded of him every time I see them and my husband doesn't want me to wear them. But!!!!!! I like them so much that I don't want to give them away.

I was there at the store when he bought this pair of earrings. It was back in 2007? or 2008? he paid about $300+tax.

This necklace is so pretty in person. Mine has three diamonds with chain but I couldn't find the exact picture online.

They've been sitting in my jewelry box at least good four years.
What should I do with these?
1) remodel em
2) wear em whenever my husband is not available lol...
3) give away to my sister (don't really want to...)
4) sell em
5) just keep em in the jewelry box
6) I don't know -_-;;;
