I can only tell you this. I have known Cali since I joined the Library and I have met MR in person. They are truly in love and I believe that when the time is right they will be together and be very happy. I hope it can be soon. They were blessed to find one another.
I just had an ugly wake up call and may not have all the time in the world to finally be with Dragon, as we had once thought. (We have no other relationships in our way, but we have elderly parents and job responsibilities that keep us apart). And even though he is ill, I still can't leave to be with him, as much as I would like to. Mean old Master insists on being "practical". Pfffft! However, I would strongly encourage anyone that has had a long term, real life relationship with their Dominant or submissive, and are totally confident that this is what they need to be happy, to do whatever they can to make that relationship exclusive.
Just my 2 copper tarns worth..... "peace" ~blizz~
