I need help ladies

So my ex an I ended very badly just a little over a month ago. Not going to go into detail but shit got extremely unbearable for both of us. We lost our son while we was together and it was and still is rough for us both even though we aren't together anymore. I recently ordered necklaces to put our son's ashes in because I'd like to have him with me at all times instead of carrying his urn around. My question is do I still give him his necklace? We aren't even speaking but I do feel he deserves it as much as I do. Help me out
