Hi all. So I was doing some work in the driveway where my boyfriend and I park our cars. It's unpaved and right under a lot of oak trees so it's constantly being drowned in leaves. While I was raking some leaves, one of our cats went and dug a hole to pee into, but when she was digging she unearthed a box. When I looked to see what it was, it was a plain wooden box that had "Mittens" written on the side. I wasn't familiar with my boyfriend having any cats by that name, so I went to ask him and he said it was his ex-girlfriend's cat. She'd apparently just left the ashes at the house after they broke up and he buried it because he didn't know what to do with it. I said I'd go bury it somewhere else in the yard, but he said to just put the box somewhere in the house again. I said that I wasn't really comfortable having ashes in the house, and we seem to not be able to figure this out. I don't really want her cats ashes in the house, I don't necessarily want to throw them away, but she didn't take them with her either so I'm at a loss for what to do. Would I be the asshole if I just buried them somewhere else in the yard again? (extra info that might be relevant: My boyfriend and his ex did not end on good terms at all, and has both me and my boyfriend blocked on social medias, so me reaching out to her to offer them back doesn't feel like an option. The box was not buried very deep in the first place, but there's been a thick layer of leaves building up over the years.)
