been there too. I have one pistol that my dad bought for me years ago. I used to keep it loaded and near me at night since I lived/live alone. When exabf stayed with me one night he asked to see it. I tried talking to him but (which I know now is pointless) and then he just passed out. He didn't remember that. The next day I hid the pistol and the bullets separately.
about a month ago I was recounting to him that I was afraid driving over this bridge in this snow storm we had and he said he didn't care, the worst that could happen would be he drove off it and died, so what. YET he wears a seat belt so DUH he obviously is full of it.
not much advice I know just wanted to say know where you are coming from.
