She took my car and was out the door crying and all mad. I don;t think i was the one to blame for this but we got into a bad argument. She took my car and i have no car to go to University. It's 9:30 and it has been 3 hours since she took of and nothing. She will not respond to my calls. I do not want to call police as it's not that serious. I just want my car back and her to be safe.
Give her a warning via text message. Then it's her own fault if she doesn't return it. BUT be aware that, from a woman's perspective, she may expect you to be more concerned about her than about going to class, so she might get angry about you getting annoyed about it. No, it's not logical, but she's having an emotional experience, not a logical one.
I'd call the cops but opt not to press charges if they find her. When someone storms out my house with my car and disappears I'd call the cops after a few hours of zero contact. She could've wrecked. Driving angry is definetly unsafe.
