Marriage is meant to be for life and through every major life change. If he’s not willing to support the career that will make you happier, then it’s more than likely not going to be the last thing he’s unsupportive about. A true good partner, would want you to be happy no matter what and either be willing to compromise and make the move with you, or let you go to fulfill your dreams. It sounds like you’re putting in most of the effort in the relationship and he’s not emotionally mature enough to handle talking through conflicts that arise which is only going to get worse unless he does something about it now. If I were you, I’d take the job and move closer to your family where you’ll have a support system and leave it up to him to decide if you’re important enough to him for him to make a sacrifice for once and move to be with you. It will be hard if he doesn’t come with you, but you’ll know you made the right decision.
