When you have something difficult or painful to say, a good piece of advice is to write two letters.
In the first letter, say everything you have to say exactly the way you FEEL it-- no holds barred, no punches pulled. Get it out of your system. Then set it aside, because nastiness serves no purpose.
Now write a second letter. In this letter, you will pare away all messy emotions and accusatory statements like "You always--" or "You never--", instead substituting much more reasonable statements that begin, "When you do so-and-so, it makes me feel..." or "I would really like it if..."
This is the letter you will actually send.
Dear Niona Eau de Parfum,
When you cause my head to jerk back that fast after sniffing you, it makes me feel as though you're hurting me on purpose. I would really like it if you did not do that.
