Hi OP.
I guess I'm him in your story:
My partner and I have both expressed a wish (more my partner) to move to his homeland in the future - Australia. Right now, in my life I can honestly say that I'd be up for it. I said when our kids (not even born yet) were all at school so I could work and meet people Id like to look at it. I'd consider it a very real possibility, maybe not forever, but certainly for a large chunk of my kids childhood. We'll review nearer the time I guess!
But I've also said whenever it's been brought up (the initial conversation was 2years ago) that if when we got to that time it didn't feel right I wouldn't. Whether he's taken that on board I have no idea. But our relationship isn't being carried forward based on future promises as big as that one given we have no idea where we'll be in say 8 years time.
He wanted to go back for a year, with me on a working visa in 2015, after I'd said in 2014 I'd maybe be up for it (he was meant to go back for good in 2014 but then he met meeee
). But 2015 rolled around and I said I didn't want too, career was looking good, money was even better. He agreed to wait, with an ultimatum (how serious it was I don't know) 2016 or he's going without me.
This years looking even better than last year, but having seen him wait for 2 years, when he'd already been in the UK for 8 and wanted to go back, I didn't want him to wait any longer. So we've booked our flights and are going in July, for 11months and 2 weeks. I will always find a reason to stay, job, family, friends. But this is important to him and he is important to me. Its a sacrifice on my part, but one I need to make and am happy in doing so.
Moving back for a longer period... I don't know about. I doubt when kids are in the mix there would be such an ultimatum. We'll discuss that when we're nearer that time.
Life changes over the years as does the circumstances we find ourselves in. You can't expect anyone to still be in the exact same place as when you had a conversation however many years ago.
I think you're both being unreasonable. You for not considering that things would have changed and for pining the future of your relationship on a relocation that he may no longer wish to go for. And Him for not managing your expectations or being totally honest over what is clearly something very important too you. I've got no advice for how to deal with it. I don't know if my post is any help. But maybe it'll help you see it slightly from the other side.
There's going to have to be compromises I guess. I wish you well with this.
