True, but on the other hand, I do feel like the way to tell someone about migraine triggers that have specific requirements for your living space is preferably *before* you move in with someone after a year and a half of quietly changing things in his apartment without telling him about it. This is a situation where two people mutually aren't trusting each other and using each other's mistrust to justify their own.

On the *gripping* hand though, if his first thought when his "very environmentalist" girlfriend is using slightly suboptimal light bulbs is to mansplain to her that they are less energy efficient, I can see why she doesn't tell him things.
