I do not want that weight on me.
That’s your thing then and your husband obliges you. There is nothing wrong with that.
My wife doesn’t want me to have all the weight on me, so, she takes a bit of the load from me. She does this without me ever asking her to do it. She just does it.
This whole 50/50 thing in marriage is wrong, I’m not even sure that it is 100/100. Some days it may be 50/50, other days 40/60, and yet other days 75/25, etc. It just depends on the day. Maybe she’s not feeling well, so I do more, and the reverse is true. We support each other day in and day out and pick up the slack when needed.
