Potentially life changing decision to make. Input needed.?

It sounds to me that your destiny lies in Japan! There is an old saying (for what it is worth), "why do you want what you know you cannot have?" Do not let this relationship put an end to what you know in your heart is your path. Perhaps this person is, in fact, the one for you and if so, it will come to pass. Take some time to look behind you (your past) and see where you have been going; then, look forward and see which of these two paths line up with the direction you have been going. Don't hesitate; take the path that lines up the best with your past direction and don't look back.
