Loss (regardless of type/circumstance) can take a lot of time to come to peace with.....

If you re-read your post....you gave a lot of reasons why you shouldn't move and very little reasons why you should. I think you already know that you are not ready to make the 'move' at this time.....

Personally I think your ex sounds like a very selfish person.....and you are in love with the 'him' that you wished he was, and are forgetting the 'him' that he really is..... did he treat you well while you were together? did he spend the time with you that you would like in a relationship?

Also, just because he was not 'the one' for you, doesn't mean you have to feel hatred toward him....so don't confuse 'caring' for him as a person as still being 'in love' with him.
