Perhaps giving it back would be a good start for your recovery process. I feel like I wouldn't want to keep it because of the crappy symbolism behind it. You take care of yourself and enjoy your new year! Who knows who you'll meet in the future OP!

Don't worry OP. It sounds like you're way better off without him, and you'll find the right person when the time is right!

Once a gift is given you can't take it back. I say keep it.

That's so rude! You should steal his idea and sell it for your own cash.

he gave it to you! it is yours. he has no claim on it unless you want to give it back. maybe instead of keeping it, you should see about getting rid of it so its not a constant reminder.

you should sell it and buy yourself something nice

Did you give him a present? Cause I can't blame him that much if you haven't given him anything. Especially if the gift was only supposed to be opened on the 25th. That said, unless that was the case, it does sound like he is being a dick. Especially as it sounds like it was his choice to break up.

if you like it, keep it. who cares where it came from. and if you don't like it then return it and keep the money for yourself.

I hope you stood up for yourself and told him no. Asking for a gift that he gave you before you broke up back is a dick move.

Don't return the gift: You have a 0% chance of ever getting back together with him, but a 100% chance of keeping the gift. Meet him to return the gift: You might have a 5% chance of getting him back and an 8% chance of keeping the gift.
