My advice is "no." I have experience moving internationally with young children with my DH's job, and we have several international couples in our circle of friends. My reasons are:
- Your children are very young and you are already struggling with depression / anxiety. Moving at all increases the risks to your mental health. Moving away from your support system makes it worse, adding in a different culture makes it even worse. It's a recipe for you to lose your mind.
- Your marriage is already strained with different goals/dreams. Imagine that you move, and it just does not work for you in huge ways, but he wants to stay. You would be trapped. Your ability to take the kids and leave would depend on the laws there. There are women who end up divorced (because their husband screwed around or whatever) but have to stay in the country they relocated to for his job because they can't take the kids and leave. I know another woman who moved back to her home county without her only child, after her husband had an affair with a work colleague.
- Don't assume you will be able to work there, or that any one will hire you part time. You have no idea what will happen. You have a great deal set up where you are, and walking away from it could make it very difficult to reenter the work force at a later time.
- Moving internationally adds some elements to a relationship that are red flags for abusive / controlling relationships. I don't mean that all spouses driving these moves are abusive / controlling, just that there is a weird overlap that can play into an unhealthy dynamic
.
For example, isolation. The move would isolate you by not only by taking you away from all friends and family, but also by putting you where you don't speak the dominate language but he does. Abusers isolate their target.
Another example is that everything will revolved around him and his job and what he needs. Obviously, your needs won't come into the planning (or else you would stay where you have support and a job). Again, this is a dynamic is abusive / controlling relationships, and international moves can easily play into it.
If a marriage is 100% healthy, then the two people can fight against those kinds of things to make it truly work for both people, but if a man has ANY controlling / abusive tendencies, an international move just gives him a great excuse to treat his wife badly.
Because your husband already lacks empathy for what you are going through, I think it is highly likely that your needs will not be considered if you move.
Your biggest concern seems to be that if you don't so this, he will resent you. Why isn't your biggest concern your emotional health? Or that you will resent him? Or that it will make it harder to restart your career? Or that he will want to stay longer than 2 years? There are so many other things besides him being pissy about not getting his way.
He’s a ‘why not?’ type and I’m a ‘what if?’! I find myself worrying about it but don’t want my anxiety to hold us back
There are a lot of reasons "why not," as listed above. I can list more if you like.
It's one thing to not want anxiety to hold you back from fully living your life, but it's quite another to give away all your power to live someone else's dream (or just their passing whims).
And holding who back from what? Holding him back from doing whatever he wants to without considering the effect on you or the children? or holding you back from human contact, employment in the larger world, and a sense of stability?
How is this move a good thing FOR YOU? Since it isn't, then your anxiety isn't holding YOU back from anything positive in YOUR life.
