There is a big, wide, wonderful world out there, filled with men who are caring, truthful and not addicted...the end of this relationship is not the end of the world or your life. In fact, by letting him go, your life will rebegin, you will have a chance at happiness and peace.
IMHO, it is a bad move to go and see him, your recovery has just begun, you are in no way ready to face your addiction to him head on.
This adventure will set you back...in fact, just talking to him has already done that...think with your head not your heart, you are making your heart do something it is not equipped/designed to do.
