Moving on is not impossible, I don't mean to sound harsh, but you are the only one standing in your own way.

Instead of accepting his answer of "don't trust a drug addict" etc, you choose to believe there MUST be more, and you get stuck on the belief that you are owed a more indepth or more meaningful explanation.

Instead of focusing on the fact that you were rejected and use that bitter hard truth to move on, you are fixated on why were you rejected. Why is inconsequential at this point, its been months and the why's he's given you haven't been good enough.

In short my dear, you are complicating your own life. Push him off of this darn pedestal you've placed him on and see him for what he is.
