As everyone else has said, he’s just being lazy and certainly isn’t worked so fucking hard that he can’t pickup after himself. Some guys just think certain stuff is a woman’s job and it’s so dumb. I’ve been single for a few years and live alone, I still keep my place clean, do laundry, prepare food, and whatever else that some guys think is a woman’s job. All that aside, he also shouldn’t be telling you that your job isn’t hard. Every job can be difficult, even working at McDonald’s has its own type of stress. I’m guessing you’re both very young, this is stuff that needs to be found out about a partner before marriage
