I'll answer this for the live-in boyfriend:
He is the oldest of 5 brothers (ages 23, 21, 20, 19, 7) and one sister (age 14). His mom does not work and has a full meal on the table when his dad gets home from work at night...and she packs all of their lunches. She does all the laundry and more or less any cleaning that is done. The only one in that house who has ever been made to do ANYTHING is his sister. I feel bad for her because she is nagged all the time to help with the dishes, laundry, etc. Our of his brothers, my boyfriend is the ONLY one who ever did anything in that house...and even that was limited. I know he would clean up, but mostly only when he knew I was coming. If he didn't take the laundry downstairs, it would sit there until they had no clothes. Haha...boy, was he in for a shock when he moved in with me. I clean plenty, but I do ask him to help. If I cook supper (sometimes he does, but I usually get home from work before him), then he does the dishes, or vice versa. I wash his street clothes, towels, etc., but he washes his work clothes. I hate packing my own lunch....there's no way I'm doing his. I have to say, he's adapted pretty well and even does things without being asked once in a while!
My parents both worked while I was growing up, and while the division of labour was a little more even, my mom still did most of the housework, cooking, laundry, etc. She still packs his lunch for work and does all the laundry (I don't think my dad would know how to do it). My mom has spent some time in the hospital both when I was in high school and now that I'm out of the house, and I remember having to pick up the slack because my dad wasn't very self-sufficient. I swore I would never let a boyfriend/husband be like that.
Now, my brother...he was taught how to cook, clean, and do laundry, but is just too lazy to do any of it!
