Yesterday when I came home from work the bottle was still on my altar, but it was mostly empty- only about two ounces left.

I knew he had drank from it, and later in the evening asked if he did. His response was... weird. "Yeah. I saw some was gone from it already, so....I'm sorry"...

Our relationship is currently in a tumultuous state and has been for some time. I didn't bother saying anything more, it was obvious he knew why I asked, and almost anything these days triggers serious fit throwing- screaming and stomping about- from him. But it REALLY got to me. It isn't the first time he's not respected my magical tools and supplies. (in a drunken rage he once swept all 7 of my oil lamps from their shelf to the floor, in another while traveling threw a bag with my St. Martha statue and other items across the car, scattering the bag and chipping the statue).
I am working to either end the relationship amicably (there are complications to doing this quickly and easily) or address the issues causing the problems (my preference but after many months of trying not looking too hopeful); but in the meantime I really feel he is sabotaging my work to improve our situation, whether it's purposeful or not I can't say.
What can I do to keep his hands (and mind) off my hoodoo and respect my work? My resources are limited but I do have devil's oil, banishing oil, FWP, Van Van, Crown of success, and Master key, and the baths and sachets of some of those.
