What are your boundaries and consequences for a snide remark?
What are you boundaries and consequences for rude facial expressions?
Put you answers down on a sheet of paper, so you can read them over and over.
Once you state your boundary and provide you consequences the gauntlet is laid and there's backing away or do overs.
So you have to prepare yourself to react not in anger but in confidence and calmness, if you react in anger you are going to say things you can't take back.
IMPO (In my personal opinion) Try to create boundaries and consequences around facial expressions and snide remarks makes you look weak and petty. The best way to deal with her is to rise above her being petty and present a calm and confident man.
She makes a rude facial expression, you look at her calmly and you don't react at all, because you know what you said makes sense and is not wrong/you're right. Or maybe you did something wrong, but you correct yourself and get it moving.
Remember, you aren't trying to go back and forth with your W, your are showing her a new and improve man. How does a new and improve Core acts/reacts and presents himself to the world.
Onward and Forward.
