Ok m'darlin, this is a tough one!
If trust wasnt an issue, I would have said, give it a go, as that would have been all you could do, as its clear his mind is made up.
However, you are going to be the one who will struggle with this the most as you lack trust in him, and are feeling hurt that he would move so far away without considering the impact it will have on you.
For him, he is blinkered by the excitement of a new job and opportunity, so wont see the downsides, in his head there arnt any as its a positive thing for him, and therefore will think that you are being unreasonable to have issues with this, when he sees there are none.
If this is going to work, its down to you, You will have to make compromises, and accept a realtionship thats on his terms, and all the while questionning his loyalty and motives. If you love him and dont want to lose him, and can take all of this on board, then give a go, see where it leads. If all the above sounds like your going to end up stressed, heart broken, and damaging your self esteem, then its time to move on. You have to ask yourself, can I live my life as an attached woman, but rarely seeing the man I am attached to? Such relationships work, but they are bloody tough, and thats even where there is complete trust and a very strong bond.
