For me, the in-between view would be to avoid either thought. Just think of it as what you are doing now. Right NOW you are moving out. That doesn't mean he is going to ask you to come back, but neither does it mean it's over forever. You simply need to take it day by day, doing what is best for YOU on a step by step basis. Think of it just as another step in this journey -- i.e. it's about the journey, not the destination.
