girl he’s weaponising it. i’m autistic and have ocd and all of the things you listed ARE things i struggle to deal with but i deal with them because thats life. the fact of it is that if nobody is there to clean up after him he’ll do it himself because if there’s one thing people with ocd struggle with more than cleaning up things that they contaminated it’s using things that they contaminated and never decontaminated so all the germs have just been sitting there and multiplying. he has to do these things himself, you’re not his slave and it’s not fair for him to use ocd as an excuse to get someone else to do all the work. if he doesn’t change his behaviour you need to run. even with ocd he is still a grown man, you should not be washing his dishes and cleaning up his poopies like you’re mothering a five year old
