We split it all. We both work so why should one person do more housework?
When I was 12, my mother taught me to cook, clean, sew, and do laundry and I've been doing it ever since! She told me I would not need a woman for anything but the obvious! LMAO I still can use a sewing machine and I do my own laundry. For cooking, me and my GF take turns. For instance, if it is my turn today then we eat what I make for the next two days. The person that cooks can make one meal that will last for two days or make a new meal each day...their choice. The downside to that is if the meal is bad, you're screwed or need to eat leftovers...if they are good!
But this does save on doing dishes, cooking, gas, etc.
We even keep our own money from our jobs. We split the bills and can keep the rest for ourselves. We don't have to ask the other for money, etc. but will combine it if we want something we each cannot afford for the house. Actually, it works out very well and there's a lot of less fighting over money...unless someone is not paying an important bill. LOL
