Linder, I am so sorry to hear how you were being strung along. Been there, and it hurts.
PDM has it right. When I had to deal with this kind of thing, I would find some kind of new activity to throw myself into, as a way to distract myself from ruminating over (and over and over) the past. It becomes a life saver. Eventually you realize your heart is healing...but it takes time, as you know. Hugs!
