So you won't tolerate it; that's easy to say, what are you going to do if she "glares" at you?
Be careful not to cross from boundary to controlling. For example, you don't want to say, "Don't you ever glare at me again". instead, say, "If you can't have a respectful conversation with me, I'll leave the room." Then do it. In mid-sentence, if you have to.
And expect some blowback - the first 10 times you do this, you'll probably get horrible crap; but when you do it consistently and fairly with no emotion, you'll see a different pattern emerge.
