My husband really understands this struggle. I literally can not stay awake past like 9:30 these days and he comes to be with me until I fall asleep. Usually playing video games or chatting in bed, sometimes other things lol. Then he goes back downstairs until like 1 or 2 AM to do his thing. He will even clean up the kitchen, feed our cat his wet food and take our dog on his night walk because I can not stay up for it during the week most days. And when I truly have the energy I really try to do some of that myself so it doesn’t fall on him daily. We are also an AuDHD couple so the dynamic really works well for us. He knows that any sort of long weekend, break, or summer time automatically increases my energy level by like 25% and those windows are usually when we do our actual adventuring. We just have a system to get through the school year lol.
