This might sound a bit ridiculous, but I've been with my partner nearly 9 months, we're both separated with dc etc so have our own homes and no plans to merge, but our standards of cleanliness are so different and it's starting to really have an impact. We have eow together and increasingly I don't want to spend time in his house as it's so unclean. Now, I'm not a clean freak and probably only clean my bathroom etc about once every 2-3 weeks (it doesn't get that dirty with just me 50% of the time) but if something looks dirty then I'll clean it. I don't know if he just doesn't notice it but he also happily wears obviously dirty clothes quite often. If I make jokey comments about it he gets a bit funny so I don't feel I can come out and say anything. And I do not want to get into a dynamic where I clean his house... 
He's a lovely kind man and the relationship is otherwise good. Has anyone else had this issue and managed to resolve it?!
