Would I be wrong for this?

My boyfriend has bipolar and takes Seroquel at night because without it, he has a hard time staying asleep through the night. One of the side effects he gets is extreme hunger, but it happens when his pills are on the verge of being full blast, so he’s so out of it that he is awake enough to make and eat it but by the time he’s done, he isn’t awake enough to move very far. So for a while now, he’s been using the end of the bed as a garbage can. He’ll eat leftovers of fast food, make stuff in bowls, have snack foods, etc. - sometimes not even finishing all of it - and just leaves it at the end of the bed. He does it every single night and doesn’t clean it up so it just piles and piles. I want to say it’s been about a month since he’s past picked it up - we’ve been spending the last couple weekends cleaning and I’ve been mentioning that I want him to clean it & between me asking AND him saying on his own that he plans on cleaning it, I didn’t because I assumed he would’ve gotten it done by now. But he didn’t. I know a lot of people would say “I would have done it by now” but I ALWAYS clean up after him, then do 99% of housework AND majority of childcare (we have a one year old and I’m 37 weeks - SAHM.) I get really fed up with having to do basically everything- he’s not a little kid 🤦🏼‍♀️ His pills wear off next day and he could take them down, he’s just fucking lazy with it. Today I woke up and saw 2 fruit flies in that area. I’m just really at my wits end with it. (This isn’t the first time we had this issue - last time he hid a dish and forgot about it bc he hid it well and it grew maggots). I want to tell him that I’m putting a small garbage can down there and telling him that he is responsible for changing it and bringing down any dishes before it gets gross. But I didn’t know if that would be controlling.
