<human>: Can you provide a brief rundown of the text in within 3 sentences?

I'm a 28/f. I live with my bf of almost a year who is 26. I knew he wasn't exactly tidy
 when we moved in but I'm a weirdo who doesn't exactly mind picking up some slack in that area if I know it makes his day a little better. Well I've created a monster. Time to time he'll do a major chore but day to day he doesn't lift a finger. He'll undress and leave his clothes in a pile under his feet. I've tried waiting to see if he will get them on his own time but they spread like moss until you can't see the floor. He'll let dishes pile up all over the kitchen. Wet towels on the wood furniture (this ruins it). I've casually mentioned the problem or ask for a hand, he tells me I'm OCD, to relax, but the next time around its the same thing and I DO NOT want to nag. I can't relax in disarray so how do I show my man how important the little things are?
<bot>: how do I get my bf to not be a total slob without sounding like a whiny, nagging housewife?
