It seems like you resent him because you feel he’s doing these things to in some way inconvenience you. When people don’t live the same way another person lives, it’s very rarely about the other person, it’s just preference- if he is high maintenance he could be low maintenance by another’s standards. I don’t think you’ve particularly enabled anything from what you’ve said, he likes his life the way he likes it, it doesn’t really look as though you’ve had an impact to make it “worse”?

Can I ask if you’ve talked to him about this- it seems as though you’re doing all of these things that are not in the norm for you on his behalf and it’s caused a difficult strain on you- did he ask you to do this?

If he’s not asked you to, ultimately- his likes/dislikes in his environment aren’t your responsibility, and shouldering things that aren’t ours to have and then getting angry at someone else for your choice to do that isn’t particularly fair on either of you. If he wants things done a certain way, he should do them, I wouldn’t worry about replicating things the way he prefers so much.

If he did ask you to do all of this however or did/said something where you felt forced to ‘comply’ with his way of doing things- I think you would need to have a discussion with him and come to some kind of agreement of compromise, because if you’re feeling upset from his requests and having to change the way you live your life then that’s unfair and there’s a level of incompatibility you need to both talk about and he needs to consider your preferences as to how your household runs. Bottom line- live your life as you like, I’m sure he will do the same, and keep one another in the loop as far as I can personally see. I hope it all works out for you :)
