It's not just you, we do it all.
I think we are wired that way.
Actually my husband and I split the bill paying responsibility, he has someone mow the lawn for us, he pitches in and helps with the dishes from time to time, and takes the trash out once in a while. Occassionally he will vacuum, or do laundry. I don't like the way he does things though. Leaves water on the counter and floor when he does dishes. He doesn't hang up the laundry right, or fold correctly. I used to be very picky, but over the years, it's like who cares. As long as we are healthy, happy, and it gets done, hey we're okay.
We both work at stressful, but rewarding jobs. All in all, even though he helps, I do most of it, while he is surfing on the net, piddling with a car he's rebuilding, or relaxing. But, it could be worse. Bottom line, he's loving & faithful and my very best friend.
