Hi there,
I absolutely feel your pain. I have been here for 8 years and have been pining to back for most of that time, getting stronger every year.
After years of trying to convince my partner of the positives of moving, and explaining my pain in staying. He finally said ok, let's give the move a go. It came as a huge surprise.
Now that we are starting to plan for our move, (perhaps late this year or next). There is a part of me which is seeing the beauty of Australia. Leaving our comfortable lives here to start again is daunting, so much more than it was when I was just dreaming of returning. Suddenly both options sound good.
My point in sharing this is, don't give up on your partner coming round, find the positives, do the holiday back when you can. I found something he loves that he can take advantage of there (In our case a change of career for husband).
Everyone's circumstances are different, but don't feel bad about the sacrifice he would make moving back, you have made a big sacrifice too.
