When their dopamine rush affects you negatively

Guys...I'm struggling with managing my own reactions and behaviours when it comes to my husband's dopamine rushes. He gets the dopamine rush, buys the 'thing' and then it's discarded in a pile (like, literal pile) in our house or backyard or whatever. Or he makes the grand gesture or declaration that he's going to do something and we ALL have to get in line.  Or some times, the purchase doesn't even MAKE it to the pile... it's still in the fecking box/wrapper sitting there for MONTHS if not YEARS. And the projects! The dopamine projects are everywhere in my home. I want a peaceful, reasonably clean home and I haven't been able to use my kitchen table but for 1 week out of the year practically and there are pending projects EVERYWHERE. 

I'd love to say that we've chatted about it and it's just something we have to live with but he doesn't acknowledge it and bringing it up even is a fight or the defensive shield goes up or whatever. it's just overwhelming and horrible to live with and in. And the example it sets for our son is crappy too. 

It feels as if I do the 'radical acceptance' on it, that I'm just rolling over and letting it be. But I want it cleaned up. Or finished. Or sold. Or addressed even and just either use it or get it out of the house! 

But in all seriousness, I know that I can only control MY actions and words and all that but this is really affecting me. I'm not sure how/what to deal with it. I dont' want to live like this to be honest. I know this. But have no idea where to even start.
