I agree. I made the mistake of dating a guy once who was absolutely filthy. While he was smart and hardworking, his house was a disaster. I would find out later his parents lived the same way. He would let dishes pile up on his home desk (he worked as a programmer). For example, milk literally curdling in a glass he used as an ashtray for his discarded cigarette butts. I tidied up now and again, but after a while, I felt more like a surrogate mother cleaning up after a teenager than I did a girlfriend. It isn’t my job to clean up after someone else on a regular basis. If a guy can’t manage to keep things relatively clean, I’m out.
It was one of several dealbreakers I acquired in my dating experience.
