I actually recommend as little actual counting as possible in a life partnership. But, when there's a sense of injustice brewing between you, some counting is inevitable, and so my advice is to count using as broad a scope as possible. It's not just hours worked or chores done, either, and it's not even just about the household - it's a system of Whole Marriage Thinking. It's about hours worked, chores done, goals supported, emotional needs met, everything. What it all takes out of you, what it all gives back. It all factors in.
Carolyn HaxOne helpful thing to keep in mind as a retort-stopper is that you won't "win," you won't change anyone's mind, you won't change any votes, you won't make the atmosphere in the room any better, YOU won't feel any better.
Carolyn HaxPlan your own vacations when you want to, and plan a suitable combined vacation with this other family when you want to. If they freak out at your planning your own vacations as you see fit, then let them. Bowing to unreasonable demands because someone will make you pay emotionally if you don't is not a healthy option.
Carolyn HaxFor me, the greatest source of frustration was trying to work with a willful child when there was something else I wanted - say, to get the child to go to bed so I could have my own time. Just the promise of the time, and feeling that promise slip away, was enough to introduce a whole other element of stress into the encounter.
