I like to analyze my dreams using a dream dictionary for what stood out to me the most. A lot of the times the dream dictionary is bang on. Its just my subconscious telling me what's going on. In this case, would him moving be a good thing or a bad thing, do you have fear surrounding this event? Is it your resistance towards this even that maybe if he moves he will be out your life for good? There are so many possibilities but only you know deep down in your subconscious mind what this event would means as dreams are always open for further interpretation.
