Big goals cause a different kind of argument from daily spending.
With daily spending you can fix it next month.
With a house, children's education or retirement, the choices last 20 years, and couples often want different things.
One wants to buy a flat now, before prices rise again, and take a 20 year home loan.
The other wants to keep that money free for the kids' school and college, because fees keep going up every year.
Both are thinking about the family. That's the hard part.
Retirement is the one most people push to later.
In your thirties it feels too far away, with school fees, EMIs and parents' medical bills all arriving at once.
But the person who worries about it often feels alone,
like the only one thinking about age 60 while everyone else thinks about this year.
Even a small monthly amount started early grows into something real by then.
There's usually no single right answer.
What works for some couples is each writing down their three biggest goals, separately, and then comparing the two lists.
Often they overlap more than expected, and the fight turns out to be about the order, not about what matters.
A flat in five years instead of now. College savings started this month instead of someday.
That kind of middle ground is easier to find once it's on paper.
Some couples even stick the list on the fridge.
