You need to do what's best for the both of you and no one else but the two of you know what that is.
My boyfriend moved 500 kilometres to live with me and by doing this he threw away a huge chance to start a 3D-animation studio. To built up a company with a friend.
Later on he figured out he should study so he applied to a college 1000 kilometres away and were accepted, of course. This time I followed him. Would I rather have stayed at home close to my family? First I thought so, but today I don't regret moving at all.
What I'm trying to say is that it's all about giving and receiving, sacrificing and gaining.
