You got a valid point on confronting her if she doesn't fulfill your standard.
However, if you confront her with emotional outburst (getting mad, raising voice etc.) then you will subcommunicate the following:
1) you're easily affected by her action. She can act consciously and predict how you're going to react to it. BAD.
2) you're insecure. If you're a respected and powerful man, you won't be fazed by small distractions around you, unless if they are really important issues.
3) you're needy. Let's say if you don't care about this girl at all, if she starts ignoring you for days, do you respond at all? Nope, you just do your own thing and move on.
4) you're paranoid.
BTW, being needy, emotionally affected, insecure and paranoid is a sure way to lose her for good.
I hope you know this.
