I had an altercation with my previous employer (more specifically a senior manager) and felt that leaving was the best option (wasn't sacked). Also the company was cutting corners and I didn't feel comfortable.
After that soon found a job in my previous (unrelated) profession on more money (and great conditions), and soon kind of slipped into this and the stability appealed to me (and my wife) and well the rest is history.
The reasons aren't simple but I want to go back, divorced, no responsibilities, some financial stability, and the chance to start my life over.
Appreciate the encouraging responses.
