Wife / Girlfriend rage

If she's insecure enough about your relationship to feel the need to compete with a CAR, you need to find someone else. A real wife/S.O. should want to support your hobbies and interests, not see them as a source of jealousy. IMO that's just bullshit intolerable behavior.

This. Time for a new girl, one that doesn't mess up your stuff behind your back. That's childish. Explain to her that is the reason the relationship is over.
