Ditto what LoginName said. You give many of us, especially me many times, great advice. I too can't answer if you should move to Alaska or not. On the one hand, your H wants you up there because he misses you. But on the other, he can't let go of the idea that he needs so much financial security. I don't know if your H grew up poor and maybe he has fears about that.
How deep of a conversation have you had regarding your R with him? Does your husband know how much you need to be with him? Have you ever mentioned divorce to him? How about a DB coach? Do you have one? Does your husband realize the predictiment he is putting himself in with his R with you, and of loosing you? Does he realize that if you were to file for D, what kind of R will he have with his children?
I am sure there are many opportunities to move back home and work there. Please suggest to him that he is scared of the future of not having enough to provide for his family. Someday were all going to die, and he will have regrets of not spending enough time with his family. I am absolutely sure of that.
Does he still go to church? How is your H's faith with God. I know I don't seem to offer you much help, but life is so short compared to all eternity and your H is risking too much to loose his family. Is he that stubborn, or is he that scared of not having enough money which he can't take with him anyway? CY
