I'm sorry you're feeling this way. Have you talked to him? I think women tend to be more subtle about things and expect guys to pick up on them but they don't. They need things to be more direct.
I understand about moving away - although we're not as far as Alaska, I followed DH to Arkansas and now to Ohio which is 9 hours from my home. I've made wonderful e-friends over the years and I jokingly call them my 'portable friends'. They've really saved my sanity on MANY occasions and have become some of my closest friends.
It's understandable to feel unattractive. I never really had body image issues before, but when I was pg with DD1 it hit me with how huge and self conscious I felt, before my belly got super duper obviously big. It was more of a shock because I wasn't expecting it, but it did get easier to deal with as my pregnancy went on.
Good luck and I hope you feel better soon!
