Tia - I don t have a mantra but do have some advice. You said you broke up with fiance because he was flaky and didn t keep his promises. Still, you didn t break up with him until Dr. Michael showed up.
Assuming your assessment of fiance is true and not just rewriting history in order to dump him WHY did you stay for 14 years with a guy who wasn't meeting your needs?
Seems to me you need to figure out what this was about before you can have a healthy relationship with Dr Michael (especially since there s a risk you might be his rebound?).
