When I was studying in England, I shared an apartment with a Korean female student, so I could share it, and I also had a friend who communicated with me every day. Besides the rent, the water and electricity meters should be paid together, because it is difficult to calculate their respective consumption in detail, so I made an agreement with this Korean girl: I will pay the water and electricity, broadband and snacks every month (which will cost me almost 200-300 pounds more), and she will be responsible for helping me wash clothes (excluding underwear), cook and clean the room; We live happily together. Then she had a boyfriend, and we were still cooking together.
These are incredible things in the eyes of China people, but they are real. Someone asked you why you didn't find a same-sex roommate. That tells you that in Europe, where homosexuality is very common, your behavior directly affects others' views on you.
But if your wife doesn't have a legitimate reason to "do laundry and cook", it's not normal.
