To answer your last few questions,

I will always be second, and I do believe she is willing to share, but she does not wish to participate.

As for moving it would be in the same country, to a different province.
My b/f will not be moving with me, he has chosen to move elsewhere and I have made the decision not to join him.
I am not moving because my Master is there, I am moving because I had made the decision to move away a while ago and I would have considered being close to my Master, but it just so happens that where I wanted to go, was closer to where he was located . As for seeking out another couple, I may do so in the future, but things are complicated enough as of now, so I will wait until they are settled down, and I can think more on it.

For now I am happy with things and the way they are going. They could change with time, but I am in no rush with anything, for now I am going to let things happen as they will.
