Can I insist to my boyfriend not to use the fluorescent kitchen light?
Why? Does that light bother you?
I can't stand the glow fluorescent lights make.
If fluorescent lights really makes you nauseous, then your partner should honor your request. If he cares about you, what you are asking is a small thing to ask for.
The light is fine. He just doesn't care about my needs.
If you feel that way, then you need to speak with him. You'll never fix these things if you are silent.
