@goforgold,
To some, their deceased loved ones ashes are all that they feel they have left of the person the cared so much about. While I personally am not a fan of cremation, I do understand it. My father passed away 10 months ago, and my mother keeps his ashes in a beautiful mahogany box I ordered that has been personalized in his memory. To some it may seem "creepy" but there are days it brings my mother great comfort to just see or touch the box. On the other had, my step mother in law did everything in her powers to rid my father in laws house of his past wife presence who had passed. All it has done is create hard feelings and resentment among many of the family members. It is unlikely that your husband is still so in love with her he cannot bear to dispose of her ashes, but keeps them out of loving memory. or possibly even her wishes. Try to respect that, and not be creeped out by something that obviously means so much to your husband. Respect goes both ways, but pushing the issue of him spreading/disposing of her ashes is apparently a sore subject. So, instead of causing tension, maybe a mutual solution would be appreciated by both parties. The cremains box I got for my father looks like a decorative piece on a shelf in my mom's office, not an urn of any kind. No one has any idea what it contains, so perhaps something along those lines would be an option your husband would be open to. I hope you can come to an amicable solution, soon.
