fight with gf, judgement on my actions?

[Colonel Kataffy]

Throw her out and don't talk to her for a couple days. She'll then try to make up. Once your made up, she'll pick another fight. This is a test. Don't get angry, just throw her out again. Rinse and repeat untill she is properly trained.

The key is to never show an change in emotion. Just calmly ask her to leave. If she doesn't grab her by the arm and put her outside. But do it calmly.
