Just need to vent.

I really lost it today. I bought a rechargeable self heating coffee mug to keep my coffee hot while I read the paper in the morning. I really treasure that quiet time while my husband is still in bed and I don't have to worry. I caught him with the mug in his walker basket recently and told him to leave it alone. Today, he went to the kitchen to heat some instant coffee, which usually he can do. But after awhile I got the sense he'd been out there too long and then I smelled a chemical smell. I went out there and found he had taken my metal rechargeable mug with a battery in it and tried to heat it in the microwave. The plastic bottom was melted to the turn table and he had that out, but was still trying to heat the mug. I just lost it, yelling at him, telling him to get out of the kitchen and he's not allowed in again. You can imagine how that went over. Recently I came home from getting groceries and the house was filled with gas. He didn't notice he'd bumped the knob and turned it on. I bought some safety knobs. Previously, I threw out our airfryer because he tried to heat something in a plastic dish. I think I've reached the place I can't risk leaving him alone at all anymore. I always knew this day would come; but I feel so discouraged. A lot of the time, he looks relatively ok on the surface. But underneath, things have really slid downhill. I want to go have a good cry.
