Nope, we have put an enormous amount of effort into being aligned with respect to our finances.
We've never once fought about money in the decade we've been together as of this week.
In that time we've tackled nearly a half million in unsecured debt, lost the much larger of our two incomes, bought multiple properties, and have spent a solid 6 figures on medical expenses, all while living essentially like students for the most part.
We once were briefly on opposing sides of a major financial decision to sell or keep a property, but only because we didn't fully understand each other's perspective on it, so we took a long walk and a few hours later were aligned as to what to do.
Frugality has actually been the cornerstone of the strength of our marriage because it prompts us to talk through literally everything in terms of what our options are, what those options truly mean to us, what happiness really is, what our priorities are, fears, etc.
When you are trying to optimize every cent of spending, that triggers a hell of a lot of contemplation of what you actually want from your life.
And when you truly understand what motivates another person and what they care more deeply about, it's easier to engage them in ways that are compassionate and don't trigger hostility.
Conflict is actually a wonderful and constructive thing when both people involved can engage from a respectful place.
