<human>: Can you provide a brief rundown of the text in within 3 sentences?

A little background to explain the situation... my father died 3 years ago, he was married to my stepmother who at the time I had a good relationship with.

After he died things became strained between us because she started going out drinking every night, refused to acknowledge that anybody else was struggling but her, spent all of the life insurance payout she was left within a year and saved nothing for any of his or her children and lost our family home that we all grew up in.

It was a shitty few years and I would have cut her out of my life if it weren't for my step siblings who I see as my own siblings and grew up with. I decided to be civil when I saw her and just have little contact with her other than this.

In the last year she has started dating someone else. I'm happy for her. I'm glad she isn't alone anymore and generally she seems to be doing better. My problem is she has moved in with her new partner and left my father's ashes in storage at her brother's house. 

I didn't want to keep the ashes originally. I don't really believe in anything after, but I know I wouldn't want to be left in a box gathering dust. My brother, not step but full brother, has wanted to spread his ashes also. We are my dad's only biological children. He wants to spread them at a place where we used to take our dog with our dad when we were kids. I think it's a nice idea.

How do I bring this up with my stepmother? We have very little contact now outside family gatherings during the holidays. I don't want to hurt her feelings, but I also don't want her to play the victim card. I know she lost a husband, but he's my dad and surely I get a say in this too? The one time I brought it up years ago she was hysterical and saying I was taking him away from her. I don't know what to do, but I don't think I can just let this go knowing they're just sitting up there in storage.
<bot>: dad died, stepmother has moved on and left ashes in storage. don't know how to ask for them to scatter them.
