Well, I think this is a fair question but I also think there isn't a direct one to one equation between a guys interest in a girl and a lack of straightening up his crib. I think, like most issues, we need to take a step back with this guy and assess him under a wider lens.
Something tells me that this guy isn't carrying himself around town like a debonair Don Draper. In other words, this guys isn't rolling up to your date in a crisp Armani suit and driving you around town in his Jaguar XJ only to open the door to his condo and surprise you with his dumpy, unkempt pad. My point? His place is probably an extension of his overall vibe and demeanor, not a symbol of his feelings about you. He might be sort of lackadaisical in his homemaker ways. If you were telling me, every time you go to this dude's house it's littered with wall-to-wall dog dung and festering mold on every flat surface, I'd have a different response for you.
Maybe I'm just a Funny Guy, wrapped like a burrito in the Christmas spirit, but I say give him the benefit of the doubt; he might be one of those loner dudes who don't really know the ins-and-outs of what a lady likes or expects. Maybe he never had an older sister teaching him the ways, or an older brother in-the-know. If you dig him on all counts aside from his lack of tidiness give it a few weeks before calling in your emotional HazMat team.
Show him by example by sharing your spic-and-span apartment. When he comments on how nice you keep your place, kiss him on the cheek and offer up a sultry, "You know what they say, cleanliness is next to sexiness."
Also does the guy have roommates? At my guy friends last apartment his roommates were disgusting, the living room and bathroom were a mess. But his room was spotless.
I know you said he doesn't pick up, but is his room completely gross and disgusting or is it just the common areas?
Depending on the level of messiness, I agree with Funny Guy, give the guy a chance.
Yeah, he probably thinks you're dirt from the wrong side of the tracks, and he has no need to impress you due to your humble, lowly origins.
Man, this is why I can't hang out with women. I can't stand them! They take almost everything as a veiled insult! Ugh! Love being a woman, though. People are so nice--except most other women
ONE individual person asks a question (fair or not), and suddenly "ALL women" are bad people. Jeez, generalizing, jumping to conclusions, judgementalism, outright sexism and misogyny, all rolled into one statement. Nicely done.
...THat person is a woman if you read the entire comment. Nice calling it misogyny.
LOL At least there's some honesty there. When I first met my husband he blamed the state of his apartment on his roommate. For some reason, I believed him! Just be prepared to clean up after him for the rest of your life!
