AITA for taking my husband's game away like he's a child

My husband has ADHD, autism, possible OCD, and some trauma. He loves to play SIMS because he grew up in a very abusive household and the only thing that got him through was his SIMS game. He enjoys SIMS and video games in general. For the most part he doesn't have a gaming addiction. The problem isn't really video games. It's certain projects that he will hyper fixate on from time to time. Right now he's been hyper fixating on building the Hogwarts Castle in his SIMS game when I say hyper fixating.... He has not slept in 3 days.... He's a teacher and the school has been doing virtual days because they have no power after a tornado hit. So he just has to upload their work online. I do not try to baby my husband because I get he's a grown man. But eventually you have to step in with him. I literally closed his laptop and took it away and told him to go to bed. He didn't argue with me and said "Sorry baby." My mom thinks sometimes I act like his mother and my husband didn't have a good mom growing up. Adding in his autism and mental health issues sometimes I do get put in that role. I'm not trying to "mother" my husband but sometimes he does not take care of himself and goes off track and I have to put him back on track.
