My husband is the same way but under different circumstances. He works 7 pm to 3 pm but sometimes he works up to 12 hours a day and then has school either from 12:30-3 or 6-8 (then goes into work late and stays longer) and when he’s home he sleeps, I feed him and send him off. It definitely puts stress on our relationship sometimes. We make it a point that our weekends are strictly family time so we can go do fun things or at least just hang out with each other. Tbh he’s a b*tch to wake up also. I know how hard he works so I kinda understand why he’s so tired. I know it’s tough. Hang in there!
