Just think back to before you started your flying training. You saw this huge hurdle and went for it. Then after all the blood sweat and tears you finally got your licence. Unless your Mr Prefect, and can breeze throught exams, understand everything first time and manage a good home life you're just Mr Average. You have had to be focused on the task in hand which might have seen to her that your not paying enough attention and that your loosing interest.
Most of the women Ive been involved with dont see all the effort that goes in to flying. They just think that you jump in and go flying every now and then. Then arrive home with a £400 invoice. Trying to get that illusive job is the worse ever (Im still trying) but people do change - thats a fact of life. Why do you think that you're a nasty person? Just because you are trying to fulfill your dream career? I think you should not be taking a look at yourself, it should be at your ex-girlfriend. She has the problem not you.
Cheer up, you'll get that first job soon enough. And when you do please recommend me too!
Women; you cant live with 'em, or kill 'em!
