My spouse has adhd and can be hyper/happy/talkative for hours and hours and hours. A few weeks ago I admitted that I had a plan to KMS and I gave him the tools I had planned to use, so that I would not go through with it. We had a conversation about it that day, and now it’s like he completely forgot about it. He just expects me to be happy. He told me I should try to be “on his level”, happier. 

Just this morning , I told him I was tired and listening to him was exhausting me and I needed a break. He can speak rapidly and excitedly for 30-45 minutes without breaks. I had to walk away. 
I just can’t bring myself to be happy. I can’t do it. Anybody else in a similar situation have any advice?
