Hey Tia. Kinda hard to give you a mantra without knowing more of the story. Why did you break up with the boyfriend/fiance? Why was he your fiance after 14 years was one of you afraid to pull the trigger?
And what does your doctor friend have to do with this? Are you just trying to find a mantra for him too, or are you romantically attracted to him?
My mantra after my exH left was let go or be dragged but that doesnt seem to fit your situation.
