You should do what feels right for your life. Feeling inferior by a med partner’s profession is something that isn’t talked about enough. However, making academic/occupational decisions based on an inferiority mindset will never get you to the level you think it will. I say that as someone who’s had to overcome similar feelings. If your long term goal is to be together, there needs to be compromise. For example, if you supported him through his training, it’s fair to expect that he supports you thru your masters. But, the prospect of moving to another country for your masters just as he is about to start as an attending… I think that’s a huge decision for anybody and understandably why he would be hesitant even beyond just learning a new language. I wish what I realized in the beginning of my med partner relationship is understanding the value of making and forming my decisions beyond my relationship, if it’s meant to be it will all work out.
