I agree with both of JNB's posts. Your girlfriend is smart. Additionally, there are many worse gigs to have than your current job/career, although the car business can be tough. I would try to find ways to improve your situation at work; including outlook, perspective, POV, Etc. While flying for hire can be enjoyable, rewarding, Etc., it is not what most people think it is. Many folks considering a professional pilot career only get to see the glamorous side and base very big decisions on that alone. At least you are here asking for advice. Best of luck
