A few points:
1) The rules of non-supplication are primarily applicable when in the dating phase that occurs briefly after meeting a girl. Relationships require an increasing level of investment from both parties to work, and occasionally that means doing something the "rules" of PUA might not approve of
2) She doesn't think you don't care. She wants you to SHOW that you do. Why? Who knows? Maybe she's feeling insecure, maybe she had a bad day, whatever. Doesn't really matter.
3) Anger is but a cunthair away from love.
